If an evacuated glass tube is equipped with two electrodes and a voltage is applied, the glass opposite of the negative electrode is observed to glow, due to electrons emitted from and travelling perpendicular to the cathode ( the electrode connected to the negative terminal of the voltage supply ).

However, a sufficiently sensitive radio telescope shows a faint background glow, almost exactly the same in all directions, that is not associated with any star, galaxy, or other object.

This glow is strongest in the microwave region of the radio spectrum.

* Electric Indigo is sometimes used as a glow color for computer graphics lighting, possibly because it seems to change color from indigo to lavender when blended with white.

The corona discharge glow at the surface of an object subjected to a high voltage electrical field is referred to as a Kirlian aura in Russia and Eastern Europe, however this should not to be confused with the paranormal concept of the aura.

The pink-orange glow running through the center of the tube is from the electric discharge which produces incoherent light, just as in a neon tube.

[...] There's one shot in particular, where Cruz enters a room in a greenish glow, which is right out of Hitchcock's picture.

Although the term phosphorescence is derived from phosphorus, the reaction that gives phosphorus its glow is properly called chemiluminescence ( glowing due to a cold chemical reaction ), not phosphorescence ( re-emitting light that previously fell onto a substance and excited it ).

A few curies ( 1 curie equals 37 gigabecquerels, 1 Ci = 37 GBq ) of < sup > 210 </ sup > Po emit a blue glow which is caused by excitation of surrounding air.

The visual sense is usually isolated by creating a soft red glow which is diffused through half ping-pong balls placed over the recipient's eyes.

When the sample is heated, at a certain temperature it will glow from the emission of electrons released from the defects, and this glow can be used to estimate the age of the sample to a threshold of approximately 15 percent of its true age.

This version of the screwdriver also appears, although never officially announced, to have a flashlight setting, as the Doctor is seen to have it emitting a continuous glow while not uttering the classic sonic noise.

In his 1967 spy thriller An Expensive Place to Die, Len Deighton misidentifies the Flemish coast tram: " The red glow of Ostend is nearer now and yellow trains rattle alongside the motor road and over the bridge by the Royal Yacht Club ..."

Many model airplanes use very simple " glow " and " Diesel " engines.

There is also a very faint, but still slightly increased, oval glow directly opposite the Sun which is known as the gegenschein.

Some commercially available invisible inks glow very brightly, in a variety of colours, under UV light.

It quantifies how objects at low temperatures radiate very little, hot objects glow a dull red and emit a perceptible amount of heat, and very hot objects ( such as the sun ) are dazzlingly bright yellow or blue-white.

In 1970, Kalevi Mattila proved the Coalsack is not totally black ; it has a very dim glow ( 10 % of the brightness of the surrounding Milky Way ) which comes from the reflection of the stars it obscures.

In practice, virtually all solid or liquid substances start to glow around, with a very dull red color, when no chemical reactions take place that produce light as a result of an exothermic process.

Because of the way detonation breaks down the boundary layer of protective gas surrounding components in the cylinder, such as the spark plug electrode, these components can start to get very hot over sustained periods of detonation and glow.

Neon glow lamps were very common in the displays of electronic instruments through the 1970s ; the basic design of neon lamps is now incorporated in contemporary plasma displays.

The sparks ( actually pieces of burning steel broken off by the harder flint ) would ignite a very small fire as they fell onto the charcloth, the glow of which could in turn be used to ignite a wood splint, after which the cloth would be extinguished for further use.

The boy thinks she is bluffing, but she tells him the signs of how to recognize a witch, which include: hair which looks like a wig, because the witches, despite being female, are actually bald, and have to wear wigs to look human ; gloves, because the witches actually have inch-long claws which they hide under gloves ; inhuman eyes, because the eyes of a witch have a red-white glow ; blue spit ; and toeless feet, which force the witches to squeeze their feet into pretty tight women's shoes which causes them to limp very slightly.

Due to the very similar mechanism of production, the blue glow is thought to resemble the " blue flash " seen by Harry Daghlian and other witnesses of criticality accidents.

Unlike most other gas switch tubes, the krytron uses arc discharge to handle very high voltages and currents ( several kV and several kA peak ), rather than the usual low-current glow discharge.

When a mercury vapor lamp is first turned on, it will produce a dark blue glow because only a small amount of the mercury is ionized and the gas pressure in the arc tube is very low, so much of the light is produced in the ultraviolet mercury bands.

A certain archaism of style, with a strong glow of colour, suffices to distinguish from the true method of Raphael even those pictures in which he most closely resembles the great masterthis sometimes very closely ; but the work of Garofalo is seldom free from a certain trim pettiness of feeling and manner. Madonna and Child and St Jerome, 1530, Dallas Museum of Art.

" I assume that most, like me, are tempted to go anyway because we will get to be ' validated ' and glow with the kind of self-congratulation that can only be bestowed by very globally visible and significant people, and we are also tempted to go and talk to spectacularly bright and accomplished people – our ' peers '.

Due to the very high voltage of the electrostatic generator designed to generate plasma in the form of a coronal discharge the wires of the antenna start emanating a violet glow.

The result is that one lamp can provide a very soft, diffuse glow or quickly adjusted to illuminate an entire room, and everything in between.

This method is referred to as glow discharge mass spectrometry ( GDMS ) and it has detection limits down to the sub-ppb range for most elements that are nearly matrix-independent.

This energy is being radiated from a relatively cool outer atmosphere that has an effective temperature of nearly 4, 000 K. It is this cool temperature that gives it the orange-red glow of an M-type star.

This triggers a traumatic memory within Hazama's mind that in turn causes 8-Man's eyes to glow red and he goes berzerk and brutally demolishes the cyborgs and nearly kills the father of his client.

Xi Andromedae is emitting nearly 46 times as much luminosity as the Sun from its outer envelope at an effective temperature of 4, 656 K, giving it the orange-hued glow of a K-type star.

When the universe was young, before the formation of stars and planets, it was smaller, much hotter, and filled with a uniform glow from its white-hot fog of hydrogen plasma.

Additionally, based on samples taken by ocean-going ships, V. harveyi is thought to be the cause of the milky seas effect, in which, during the night, a uniform blue glow is emitted from the seawater.

Their eyes are most disturbing, as they are a uniform pale yellow in color and glow with a faint sickly yellow light, lacking in both iris and pupil.

When Alba was exposed to such light, she would literally glow green — though photos by Kac showing the entire organism, including its hair, glowing a uniform green have had their veracity challenged.
