Allen, L. (1976). Time Before Morning: Art and Myth of Aboriginal Australians. Adelaide: Rigby. Research suggests that this light is likely zodiacal light, caused by extraterrestrial dust reflecting light from the solar system. This ‘rope’ is important in Yolngu mythology because it prevents Barnumbirr from straying too far from Bralgu and facilitates communication between dead and living people.

In optics, a diffuser (also called a light diffuser or optical diffuser) is any material that diffuses or scatters light in some manner to transmit soft light. Diffused light can be easily obtained by reflecting light from a white surface, while more compact diffusers may use translucent material, including ground glass, teflon, opal glass, and greyed glass.

They noticed that her forehead wound remained the same, with drops of blood still reflecting light. When her body was later exhumed, it was noted that her forehead wound remained the same, with the glistening light reflected from the drops of blood. Her body showed no signs of deterioration. Over several years, her body was exhumed two more times.

Routledge; 5 November 2010. . p. 45–. However, such common visual artifacts are simply a result of flash photography reflecting light off solid particles, such as dust or pollen, or liquid particles, especially rain, or even foreign material within the camera lens, and are especially common with modern compact and ultra-compact digital cameras. Fujifilm describes the artifacts as a common photographic problem.Cynthia Baron.

Frontal view of brown fur seal head On land, pinnipeds are near-sighted in dim light. This is reduced in bright light, as the retracted pupil reduces the lens and cornea's ability to bend light. They also have a well-developed tapetum lucidum, a reflecting layer that increases sensitivity by reflecting light back through the rods. This helps them see in low-light conditions.

306-316 (2005) EUV photomasks work by reflecting light instead of blocking light. Photomasks are made by applying photoresist to a quartz substrate with chrome plating on one side and exposing it using a laser or an electron beam in a process called maskless lithography. The photoresist is then developed and the unprotected areas with chrome are etched, and the remaining photoresist is removed.

Gustavia angustifolia is native to the dry deciduous forests of the coastal plain of Ecuador and Colombia. Pubescent leaves are beneficial in hot, dry environments such as these. The tiny hairs help to keep the leaves cool by reflecting light and casting tiny shadows on the leaf surface. In addition the hairs also provide a barrier between the leaf and the air thereby reducing the amount of exposed surface.

A whisk broom or spotlight sensor, also known as an across-track scanner, is a technology for obtaining satellite images with optical cameras. It is used for passive remote sensing from space. In a whisk broom sensor, a mirror scans across the satellite’s path (ground track), reflecting light into a single detector which collects data one pixel at a time. The moving parts make this type of sensor expensive and more prone to wearing out.

One cut or true cut beads have a flat surface cut into the bead that produces a shine or sparkle when reflecting light. Cut beads that are size 13/0 are referred to as "Charlottes." However, many people refer to all cut beads as Charlotte cut. There are three-cut beads which are "barrel faceted", meaning they start with a round bead and make more random machine cuts, creating a nugget like bead.

A unit of luminance equal to 1 / Π candela per square foot or to the uniform luminance at a perfectly diffusing surface emitting or reflecting light at the rate of one lumen per square foot. A lumen per square foot is a unit of incident light and a footlambert is a unit of emitted or reflected light. For a perfectly reflecting and perfectly diffusing surface, the number of lumens per square foot is equal to the number of footlamberts.

Rolling the aircraft caused the gyro to rotate in the same direction, which was geared to cause the opposite motion in the reflector. As the sights worked by reflecting light off the reflector in the centre, motion of the mirror would result in twice the motion of the aim point. To address this, the gyro was attached through levers with a 2-to-1 reduction. The reflector sight mechanism was mounted in front of the gyro, slightly to the left.

The eyes are bright red when reflecting light. The measurements of the forearm are 65 to 70 millimetres, the head and body combined is from 82 to 93 mm and the length of the ear from base to tip is 16 to 20 mm. The average weight is 48 grams, for the recorded range of 42 to 56 grams for individuals. The dentition is adapted to its frugivorous diet, lacking lower incisors and using the lower against the upper canines to consume fruits.

The cantilevered heliostat of One Central Park is attached to the eastern tower of the complex. Central Park's cantilevered heliostat figures as another defining feature of the building. Suspended from the 28th floor of One Central Park's east tower, it serves not only as a predominant design element to the building but as a way of reflecting light to the gardens and atrium below. It operates through a series of motorised mirrors that are positioned 100 metres below the cantilever on the rooftop of the west tower.

The origin of the resin works, which Pierce would go on to explore, refine, and create for the rest of her artistic life, is well known. In 1969 while working on a foam piece Pierce accidentally spilled some resin onto a piece of aluminum foil. She held the foil to the light and the effect of the mirror surface reflecting light up through the resin entranced her. In the beginning, Pierce poured the resin onto mirrored glass however the resin did not bond well with the surface.

Laser printing differs from traditional xerography as implemented in analog photocopiers in that in the latter, the image is formed by reflecting light off an existing document onto the exposed drum. Invented at Xerox PARC in the 1970s, laser printers were introduced for the office and then home markets in subsequent years by IBM, Canon, Xerox, Apple, Hewlett-Packard and many others. Over the decades, quality and speed have increased as the price has fallen, and the once cutting-edge printing devices are now ubiquitous.

These changes involved limiting or eliminating the artillery bombardment in areas where American forces were in the habit of withdrawing for the night, or where they were so widely spaced as to allow German troops to advance around them during the night before the attack. He also suggested using searchlights reflecting light indirectly from the clouds to illuminate the advance in the winter darkness preceding the dawn. Hitler agreed to these changes. In planning for the actual attack, Manteuffel had divided his 5th Panzer Army into three corps composed of infantry, tanks, and supporting artillery.

The Foucault knife-edge test was described in 1858 by French physicist Léon Foucault as a way to measure conic shapes of optical mirrors.Texereau 1984 pp.68-70 section 2.25 It measures mirror surface dimensions by reflecting light into a knife edge at or near the mirror's centre of curvature. In doing so, it only needs a tester which in its most basic 19th century form consists of a light bulb, a piece of tinfoil with a pinhole in it, and a razor blade to create the knife edge.

Direct sunlight and reflected light from the sky have different levels of radiation. The daylighting design should reflect the needs of the building in both its climate and function, and different methods can achieve that. Southern and northern windows are generally best for daylighting, and clerestories or monitors on the roof can bring daylight into the center of a building. Placing windows higher up on a wall will bring the light further into the room, and other methods like light shelves can bring light deeper into a building by reflecting light off the ceiling.

The P30 and P30 Pro were unveiled in Paris during a media event on 26 March 2019 which features a main RYYB subpixel array (replacing green pixels for yellow) that is very sensitive to light making it able to shoot photos in very low lighting conditions. The P30 Pro also has a telephoto camera that utilises a triangular prism (using periscope technology with lenses and camera sensor 90° offset near the centre of the phone) reflecting light giving it the ability to have 5x optical, 10x hybrid and 50x digital zoom.

A year later he enrolled in Paris at the École nationale supérieure des Beaux-Arts. He studied traditional clay modelling with the sculptor Marcel Gimond, but did not abandon his own personal style and continued carving directly on working materials with hammers, sledge hammers and chisels. Too poor to buy his own working materials, Selinger went hunting for stone blocks in the slum belt of Paris and came back with a very dense and hard bloc of granite capable of capturing and reflecting light. Granite became his favourite stone.

It gives both a sense of motion and also a dramatic new way of reflecting light. The cartouche was another characteristic feature of Baroque decoration. These were large plaques carved of marble or stone, usually oval and with a rounded surface, which carried images or text in gilded letters, and were placed as interior decoration or above the doorways of buildings, delivering messages to those below. They showed a wide variety of invention, and were found in all types of buildings, from cathedrals and palaces to small chapels.

The ice crystals responsible for halos are typically suspended in cirrus or cirrostratus clouds in the upper troposphere (), but in cold weather they can also float near the ground, in which case they are referred to as diamond dust. The particular shape and orientation of the crystals are responsible for the type of halo observed. Light is reflected and refracted by the ice crystals and may split into colors because of dispersion. The crystals behave like prisms and mirrors, refracting and reflecting light between their faces, sending shafts of light in particular directions.

For space missions, gold is used because it is useful at reflecting light, which helps to detect celestial objects from far away and gold does not oxidize so it will not tarnish, unlike most other metals. Due to both benefits, the James Webb Space Telescope uses gold on its mirrors. NASA partnered with Epner Technology, a Brooklyn-based business that has been gold-plating for generations to develop the technology to gold plate the telescope's parts. This NASA technology transfer to Epner gave the company a reputation for durable gold coatings.

When the camel exhales, water vapor becomes trapped in their nostrils and is reabsorbed into the body as a means to conserve water. Camels eating green herbage can ingest sufficient moisture in milder conditions to maintain their bodies' hydrated state without the need for drinking. Domesticated camel calves lying in sternal recumbency, a position that aids heat loss The camel's thick coat insulates it from the intense heat radiated from desert sand; a shorn camel must sweat 50% more to avoid overheating. Cited in During the summer the coat becomes lighter in color, reflecting light as well as helping avoid sunburn.

"She wasn't in a hurry at all, but she had to have known that a train was coming." he said. At the head of the train, Smalls told investigators he first noticed something reflecting light from within the crossing when it was ahead. He soon realized it was from a vehicle fouling the tracks, and immediately hit the air brakes and sounded the horn, earlier than he would have been required to take the latter action if the tracks appeared clear, in the hope that the vehicle would hear it and leave since he knew he could not stop the train in time.

At this time, the Brain receives a call from Uncle in the hospital, who tells the Brain that Fatty's death really was an accident. Uncle had accidentally dropped a bag of toy balls that night, which led to the loss of control of the bus. Realizing he has made a mistake and that the agent is innocent, the Brain runs and tries to cover the windshield from reflecting light. The agent sees and recognises the Brain as he is running, but the Brain is too late, and a blinded driver runs over the agent's wife, killing her.

Salisbury screens operate on the same principle as optical antireflection coatings used on the surface of camera lenses and glasses to prevent them from reflecting light. The easiest to understand Salisbury screen design consists of three layers: a ground plane which is the metallic surface that needs to be concealed, a lossless dielectric of a precise thickness (a quarter of the wavelength of the radar wave to be absorbed), and a thin glossy screen. #When the radar wave strikes the front surface of the dielectric, it is split into two waves. #One wave is reflected from the glossy surface screen.

Dale Nelson, writing in the J.R.R. Tolkien Encyclopedia, suggests that Gollum may derive from H. G. Wells's Morlocks in his 1895 novel The Time Machine. They have "dull white" skin with a "bleached look", "strange large grayish-red eyes" with "a capacity for reflecting light", and run in a low posture somewhere close to all fours, looking like "a human spider", through having lived for generations underground in darkness. A 2004 paper in the British Medical Journal by supervised students at University College London argued that Gollum meets seven of the nine diagnostic criteria for schizoid personality disorder.

Active optical systems triangulate positions by illuminating one LED at a time very quickly or multiple LEDs with software to identify them by their relative positions, somewhat akin to celestial navigation. Rather than reflecting light back that is generated externally, the markers themselves are powered to emit their own light. Since inverse square law provides one quarter the power at two times the distance, this can increase the distances and volume for capture. This also enables high signal-to-noise ratio, resulting in very low marker jitter and a resulting high measurement resolution (often down to 0.1 mm within the calibrated volume).

Male Wilson’s Birds of Paradise are the most colorful of all the species within the family, possessing a veritable rainbow of color. This remarkable example of hue and iridescence possesses all of the primary colors (and more) in different ways. The baby blue hue of its head is skin, not feathers, and is the result of structural color absent in any other member of birds of paradise. Yellow on the nape of its neck, followed by the crimson on its back are consistent, pigmented colors, present year-round. Its quirky, “handlebar-mustache-shaped” tail feathers are brilliantly iridescent, reflecting light to produce intense color to the eye of the beholder.

DLP uses MEMS technology, which stands for Micro-Electro- Mechanical Systems. DLP HDTV chips include hundreds of thousands of microscopic mirrors which tilt back and forth, reflecting light which is then projected onto a television screen. While Liquid Fidelity creates an HDTV image by controlling the amount of light reflecting from it, DLP creates an HDTV image by varying the percentage of the time that its mirrors are aimed toward the projection screen. The main advantage of Liquid Fidelity over DLP is that the 1080p Liquid Fidelity chip has over 2 million cells, in an array of 1920 x 1080, for true 1080p pixel resolution.

After thousands of generations of living without sunlight, the Morlocks have dull grey-to-white skin, chinless faces, large greyish-red eyes with a capacity for reflecting light, and flaxen hair on the head and back. They are smaller than humans (presumably of the same height as the Eloi). Like the Eloi, they are significantly weaker than the average human (the Time Traveller hurt or killed some barehandedly with relative ease), but a large swarm of them can be a serious threat for a lone man, especially unarmed and/or with no portable light source. Their sensitivity to light usually prevents them from attacking during the day.

Variability in the stack height allows more overall light to be reflected and this further enhances the glossy appearance, but it makes the fruit appear somewhat pixelated. In addition to simply reflecting light of a specific wavelength, the helicoid structure also causes light of other wavelengths to be modified so that the wavelength converges to within a narrow range before being reflected, which acts to amplify the light at that specific wavelength. This process of constructive interference produces the most intense coloration of any living organism. The total reflectivity is about 30% of that of a silvered glass mirror, and is the highest of any known biological material.

Radioactivity is the ability of an atom to emit energetic particles. When particles hit the target materials they may free other highly energetic particles. When the nucleus is not modified this ends shortly after the end of the exposure, much like objects stop reflecting light when the source is turned off and warm objects emit heat until they cool down but do not continue to produce their own heat. To modify a material so that it keeps emitting radiation (induce radiation) the atomic cores (nucleus) of the atoms in the target material must be modified by colliding with particles above a specific energy threshold.

Mucus provides a physical network allowing the worms to move in the seeps of seawater. An in-depth study on the behavior of S. roscoffensis in situ explains that the only possibility for the worm to move horizontally is to make a support (invisible to the naked eye) which is nothing other than a matrix synthesized from secreted mucus. By observing closely, we see that animals do not slide directly on the sand but "give the impression of sliding on an invisible surface". The author of this study hypothesized that animals, moving "above" the sandy substrate, would also receive more light by reflecting light rays, taking advantage of more photosynthesis and hence nutrient transfer for the worm.

606 He first tried again with plain muslin or a piece of white cardboard as the backdrop, but for these images he thought the contrast between the backdrop and the pepper was too stark. On August 3 he found a large tin funnel, and, placing it on its side, he set a pepper just inside the large open end. He wrote: > It was a bright idea, a perfect relief for the pepper and adding reflecting > light to important contours. I still had the pepper which caused me a week's > work, I had decided I could go no further with it, yet something kept me > from taking it to the kitchen, the end of all good peppers.

The DVD commentary for Stargate SG-1 explains that these effects are produced by reflecting light off large sheets of vibrating Mylar. An orbital Stargate in the Pegasus galaxy, with 3 station-keeping rocket packs attached evenly around the rim. The Stargate itself is nearly always filmed against a blue or green backdrop, not only making it easier to paste the vortex imagery onto the scene, but also facilitating the superimposition of the "event horizon ripple effect", which is entirely computer-generated. However, if a shot only involves an open wormhole without anyone stepping through it, the crew may choose to use a "practical puddle," which is simply a back lit screen placed in the gate displaying a video of the wormhole effect.

LEDs were chosen because they were viewed as the lowest maintenance option of the possible color changing fixtures. LEDs fit into an electrical circuit, causing illumination by the movement of electrons in the semiconductor material and making a filament unnecessary, so the bulbs never burn out and do not get too hot. Fins were added to the screens to keep direct sunlight from hitting the LEDs. Color Kinetics (now part of Philips Solid-State Lighting Solutions, which is now called Philips Color Kinetics) ColorBlast 12 LEDs fixtures are used to illuminate the tower structures and glass in an attempt to meet Plensa's objective that the towers have a light and translucent appearance, with their internal structures reflecting light from behind the glass surface.

Pęczarski's 1845 work Card-sharpers by candlelight, depicting a card whose back has been marked, possibly using wax to add lines which become slightly visible when reflecting light Card marking is the process of altering playing cards in a method only apparent to marker or conspirator, such as by bending or adding visible marks to a card. This allows different methods for card sharps to cheat or may be used for magic tricks. To be effective, the distinguishing mark or marks must be visible on the obverse sides of the cards, which are normally uniform. Casinos alter playing cards used at table games before they are sold or given away to prevent cheaters from buying them to cheat at table games.

This effect can be exploited to produce coatings that polarize a light beam. By manipulating the exact thickness and composition of the layers in the reflective stack, the reflection characteristics can be tuned to a particular application, and may incorporate both high-reflective and anti- reflective wavelength regions. The coating can be designed as a long- or short-pass filter, a bandpass or notch filter, or a mirror with a specific reflectivity (useful in lasers). For example, the dichroic prism assembly used in some cameras requires two dielectric coatings, one long-wavelength pass filter reflecting light below 500 nm (to separate the blue component of the light), and one short-pass filter to reflect red light, above 600 nm wavelength.

The procedure is simple, in appearance: the camera slows down, he heads it towards planets emitting or reflecting light, the sun,Venus, Jupiter,the moon, or towards cities at night and lets, by the movement of his hand, the light deposit itself on the support.It is the very light which deposits itself in bursts of colour, streams of oscillations and of flow on the screen, the canvas, the wall. A work that Marc-Alain Ouaknin calls "The sky at his fingertips",Marc-Alain Ouaknin, Jean Daviot Le ciel au bout des doigts, Paris Musées /Actes Sud, 2004 the title of a book he wrote on the artist. In his "Bocca del mondo", Daviot makes huge jars speak and discuss; by night they transform into planets.

The term cat's eye derives from the resemblance of the cat's eye retroreflector to the optical system that produces the well-known phenomenon of "glowing eyes" or eyeshine in cats and other vertebrates (which are only reflecting light, rather than actually glowing). The combination of the eye's lens and the cornea form the refractive converging system, while the tapetum lucidum behind the retina forms the spherical concave mirror. Because the function of the eye is to form an image on the retina, an eye focused on a distant object has a focal surface that approximately follows the reflective tapetum lucidum structure, which is the condition required to form a good retroreflection. This type of retroreflector can consist of many small versions of these structures incorporated in a thin sheet or in paint.

When the TA was reconstituted in 1947, it was at first proposed to reform the battery as a gun tractor battery, but that role was taken over by the Royal Army Service Corps, and instead 484 S/L Bty was reconstituted as 858th Movement Light Battery (Carmarthenshire Fortress), RA with HQ at Llanelli.850–870 Btys RA at British Army 1956 on.Litchfield, p. 83. With the advances in radar technology, AA S/L units were under-employed by the end of World War II, but during the campaign in North West Europe 21st Army Group had pioneered the technique of reflecting light off the cloudbase to provide 'artificial moonlight' or 'movement light' (also known as 'Monty's moonlight' after 21st Army Group's commander, General Sir Bernard Montgomery) in support of night operations.

To the extent that the helmet is jewelled, such decoration is largely confined to the elements associated with the dragons. Convex garnets sunk into the heads give the dragons red eyes. The eyebrows are likewise inlaid with square garnets on their under edges, continuing outwards on each side to where they terminate in gilded boars' heads; in addition to their secondary decorative function as wings, the eyebrows may therefore take on a tertiary form as boars' bodies. The subtle differences between the eyebrows, the sinister of which lacks the gold foil backing employed on the dexter, may suggest an allusion to the one-eyed god Odin; seen in low light, with the garnets of only one eye reflecting light, the helmet may have itself seemed to have only one eye.

King's art draws upon principles of sacred geometry to render three-dimensional shapes and patterns found in nature. Through the application of advanced design technology, and the manipulation of light and color, King creates light-responsive sculptures that interact with viewers and animate the surrounding environment.Exhibition by American Artist Ray King Opens at Taipei Artist Village, American Institute in TaiwanBarbara wolff, Light-sensitive sculpture set for pharmacy building, University of Wisconsin-Madison News His sculptures – inspired by geometric patterns found in nature—dynamically interact with the sun and artificial light, projecting and reflecting light into the surrounding environment, shifting in color and transparency and changing appearance with the times of day and degrees of sunlight. King is interested in and inspired by ancient cultures’ use of light in architecture and monuments, particularly how light and mathematics were used to further understand planetary movement and the Earth’s relation to the larger universe.

These were often ink on white paper or gold-leaf decorative wall panels that served a dual purpose of reflecting light around the dim castle rooms as well as flaunting the castle owner's abundant wealth to commission such extravagant pieces. Many of Tōhaku's earlier works are in the style of the Kanō school, such as his Maple, Chishaku-in painted in 1593. At the same time he also studied the older Song, Yuan and Muromachi periods' styles of ink painting by examining scrolls from Mu Qi and Sesshū Tōyō, which he is believed to have gained access to in his time at the Daitoku-ji temple in Kyoto. After a period of time in Kyoto, Tōhaku developed his own style of Sumie which in many ways departed from the bold techniques indicative of the Kanō school, and called back to the minimalism of its predecessors.

They also failed to detect any solar Fraunhofer lines—the fact later interpreted by Norman Lockyer as indicating that Uranus emitted its own light as opposed to reflecting light from the Sun. In 1889 however, astronomers observed solar Fraunhofer lines in photographic ultraviolet spectra of the planet, proving once and for all that Uranus was shining by reflected light. The nature of the broad dark bands in its visible spectrum remained unknown until the fourth decade of the twentieth century. Although Uranus is presently largely blank in appearance, it has been historically shown to have occasional features, such as in March and April 1884, when astronomers Henri Joseph Perrotin, Norman Lockyer, and Charles Trépied observed a bright, elongated spot (presumably a storm) circling the equator of the planet. The key to deciphering Uranus's spectrum was found in the 1930s by Rupert Wildt and Vesto Slipher, who found that the dark bands at 543, 619, 925, 865 and 890 nm belonged to gaseous methane.

Nativity, National Gallery of Art Della Robbia's earliest surviving freestanding sculpture is the white tin-glazed terracotta Visitation in the church of San Giovanni Fuoricivitas of Pistoia, dating to 1445. Although the date of della Robbia's first work in colored glazed terra-cotta is not known, his demonstrated control of this medium secured him two major commissions for the duomo of Florence: the large reliefs of the Resurrection (also from 1445) and the Ascension of Christ (1446). The pliant medium of baked clay covered with a "slip" of vitrified lead and refined minerals permitted a lustrous, polished surface capable of reflecting light and color that was beautifully appropriate for architectural sculpture.Britannica.com, Luca della Robbia, glaze on terra-cotta sculptures, accessed August 27, 2012 Whether animating the vast, somber space of the Cathedral or in the series Twelve Apostles gracing the pristine surfaces of the small Pazzi Chapel (1443–1450) in Florence, della Robbia's reliefs in this medium achieved a high level of mastery.

The distinction between the metalloids and the metals is slight. The former, excepting selenium and phosphorus, do not have a "metallic" lustre; they are poorer conductors of heat and electricity, are generally not reflectors of light and not electropositive; that is, no metalloid fails of all these tests. The term seems to have been introduced into modern usage instead of nonmetals for the very reason that there is no hard and fast line between metals and nonmetals, so that "metal-like" or "resembling metals" is a better description of the class than the purely negative "nonmetals". Originally it was applied to the nonmetals which are solid at ordinary temperature. In or around 1917, the Missouri Board of Pharmacy wroteMayo 1917, p. 55 that: :A metal may be said to differ from a metalloid [that is, a nonmetal] in being an excellent conductor of heat and electricity, in reflecting light more or less powerfully and in being electropositive.
