He noticed the light beam reflected on the enemy's objective lens.

Particle radiation is referred to as a particle beam if the particles are all moving in the same direction, similar to a light beam.

AS A door closes on the light beam that's coming back to his eye.

And that's a video, a high definition video that is transmitted through that light beam.

Long range laser scanning by sending out a pulse that's a laser beam of light.

Sonar searching beam to beam, sir.

Chiral molecules, placed in a beam of such light, interact differently with the two chiral components.

Female Voice Long range laser scanning by sending out a pulse that's a laser beam of light.

If light were made of tiny, solid balls, then you would expect that some of the particles from Beam A would crash into some of the particles from Beam B.

But it's odd that you can't see the beam of light, you can only see what it hits.

I Beam

Each year, between October 9 and December 8, it projects a vertical beam of light high into the sky.

The Fresnel lens is useful in the making of motion pictures not only because of its ability to focus the beam brighter than a typical lens, but also because the light is a relatively consistent intensity across the entire width of the beam of light.

Strunk! The beam!

When the wavefront passes through them, the amplifiers release some of the light energy stored in them into the beam.

For example, refraction, which is how a beam of light appears to bend as it passes from air into water.

Like here this is a very low light level actually.

low energy light bulbs, fibre optics and flat screen displays.

The effect on the light beam is a rotation of its plane from the original one, otherwise known as optical rotation.

And if I don't need it, I can convert it back up on the window to energy, light, and beam it,

Beam me up, Scotty.

Beam me up, Scotty.

The sun don't beam

A household disintegrator beam.

Off the starboard beam!

The spot of light from the laser beam will travel across the moon's face in about half a millisecond, which means it's traveling at twenty times the speed of light!

To determine blood glucose, the measuring beam of infrared light, for example, has to penetrate the tissue for measurement of blood glucose.

When it's dark, in a vacuum, if a person shines a beam of light straight across your eyes, you won't see it.

He notices that it seems like a door is starting to close on the light beam that's coming back to his eye.

These microscopes use a beam of electrons to illuminate things that are too small to be seen by the photons of visible light.

Packed into every linear, plane polarized beam of light are right handed and left handed parts that rotate together to produce plane polarization.

In the morning, the sunlight will shine down on the first magnifying glass, focusing a beam of light on the shot glass underneath.

I step over the beam.

He's off the beam again.

Synchronize radio beam for toppling.

Yet another kind of neuron is low threshold mechanoreceptor, activated by light touch.

Well, the rod cells in your retina take over in low light conditions.

You can't see light. When it's dark, in a vacuum, if a person shines a beam of light straight across your eyes, you won't see it. Slightly technical, some physicists will disagree with this.

A cloud on the starboard beam.

There's an infrared beam that's going across, and he has stepped into the beam and taken his photograph.
