And what the Russians are doing is they're building these detectors and immersing them about a kilometer beneath the surface of the lake so that they can watch for these flashes of blue light.

So here's what you do. First of all, as I said, don't stare at the light flash, if you can. I don't know you could possibly resist doing that.

Barely discernible most of the time, only brief flashes illuminate the battle, as when Mikhail Khodorkovsky was arrested.

It measures the absorption of light in a sample The neat thing about this is, you have light source that flickers on and off at about 1,000 hertz, another light source that detects that light at 1,000 hertz, and so you can run this system in broad daylight.

is lightened by the neighbouring suns of your eyes.

When she runs on the bombed out track of Coni Stadium, she gets flashbacks to Beijing.

This puts the spotlight on India all the more.

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.

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

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.

In sum, while there was a perilous turn back to the abyss in the past month or so, there have been some glimmers, particularly in the last week, that may point to a new beginning.

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.

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.

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.

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.

It works because numerical aperture is a function of the maximum angle of light that can enter the lens and the refractive index of the medium through which the light passes.

Also in the 11th century, Abū Rayhān al Bīrūnī agreed that light has a finite speed, and observed that the speed of light is much faster than the speed of sound.

Now that thing, light flickers across it as you move, so it becomes a kinetic object, even though it's standing still managed by how brilliantly that's done on the reflection.

Boy Oh, because the light goes only to here, not here.

When a neutrino hits a water molecule it emits a kind of blue light, a flash of blue light, and by looking for this blue light, you can essentially understand something about the neutrino and then, indirectly, something about the dark matter that might have created this neutrino.

And you'll note there's no light coming from them right now, either because they're dead or because I need to stir them up in some way for you to see what bioluminescence really looks like.

Then there's ultraviolet light.

Switch off the light. I can't get to sleep.
