This predator avoidance strategy involves the use of ventral light to break up the fishes' silhouettes, so that (when viewed from below) they blend in with the ambient light from above.

GRB 090423 was also the oldest known object in the Universe, as the light from the burst took approximately 13 billion years to reach Earth.

Studies on the light emitted by laser trapped francium 210 ions have provided accurate data on transitions between atomic energy levels which are fairly similar to those predicted by quantum theory.

What you're seeing when you put it through a prism is that you heat hydrogen up and it doesn't just glow like a white light, it just emits light at particular colors, a red one, a light blue one, some dark blue ones.

Venom emitted from some types of cobras, almost all vipers, some Australian elapids and some sea snakes causes necrosis of muscle tissue.

In 1999, world gross carbon dioxide emissions from coal usage were 8,666 million tonnes of carbon dioxide.

Hypothetically, switching off the lights for an hour would cut CO2 emissions from power plants around the world.

This puts the spotlight on India all the more.

He correctly identified this 'food of life' with the gas (also oxygen) given off by heating nitre (saltpetre).

the lampstand also for the light, with its vessels, its lamps, and the oil for the light

The candlestick also for the light, and his furniture, and his lamps, with the oil for the light,

Turn on the light, please.

Turn off the light, please.

Thermal infrared, 10400 12500 nm, uses emitted instead of reflected radiation to image geological structures, thermal differences in water currents, and fires, and for night studies.

Electromagnetic radiation in this range of wavelengths is called visible light or simply light.

Venom emitted from elapids, including sea snakes, kraits, cobras, king cobra, mambas, and many Australian species, contain toxins which attack the nervous system, causing neurotoxicity.

Superluminal communication is the hypothetical process by which one might send information at faster than light (FTL) speeds.

This ring is hidden from visible light images of the galaxy because it is composed primarily of cold dust.

The idea is to capture the carbon dioxide that is emitted in power plants and other big factories when fossil fuels are burned, thereby preventing it from entering the atmosphere.

Another method is to take the light from a light source and modulate it in an external optical modulator.

I want a blade of light across the Thames.

The light source is normally outside the body and the light is typically directed via an optical fiber system.

Turn off the light.

She turned on the light.

Garik Israelian is a spectroscopist, studying the spectrum emitted by a star to figure out what it's made of and how it might behave. It's a rare and accessible look at this discipline, which may be coming close to finding a planet friendly to life.

There's a beautiful statement on the screen that says, Light creates ambiance, light makes the feel of a space, and light is also the expression of structure.

Syria states that smoke from the oil well fires in Kuwait was transported over its territory for a total period of eight days between February and November 1991.

He would shoot his light saber across the abyss, making a blade of light, and then scamper across on this blade of light.

And we used to see the most mysterious animals out the window that you couldn't describe these blinking lights a world of bioluminescence, like fireflies.

There is a vast difference between a pure spectral yellow light, with a wavelength of approximately 580 nm, and a mixture of red and green light.

As the light is being moved from one eye to another, both eyes begin to dilate, but constrict again when light has reached the other eye.

I live cycles of light and darkness.

Several events should be highlighted.

I just barely got the lights out in time for you to be able to see those gobs of light hitting the transect screen and then just glowing.

Similarly, it will take a decade of public and private investments to demonstrate the feasibility of coal fired plants that capture their carbon dioxide.

He could moreover prove that such a wave would necessarily travel at the speed of light, and thus light itself was a form of electromagnetic radiation.

He considered the astral light the medium of all light, energy and movement, describing it in terms that recall both Mesmer and the luminiferous ether.

Artificial light is produced by electricity.

Blinded by the Light

A green light will be activated at the start of the speaker's statement an orange light will be activated 30 seconds before the end of the three minutes and a red light will be activated when the three minutes have elapsed.

This highlights the real deception by both sides.

It is the highlight of the Three Manly Games of Naadam.

The amount of light received depends upon a combination of several factors.

It is not clear from the public record how successful the Shrimp light pipes were.

And it explodes, and it shines as brightly as a billion suns for about two weeks, and releases, not only energy, but a huge amount of chemical elements into the universe.
