Light pressure is equal to the power of the light beam divided by c , the speed of light.

I was wakened by a beam of light shining through my window.

Fizeau directed a beam of light at a mirror several kilometers away.

In a laser, what makes laser light so different from the light above my head here is that this light is incoherent many different colors and different frequencies, sort of like the way you clapped initially but if you were a laser, it would be rhythmic applause.

The witch cast a spell and a beam of light shot out of her wand.

Effortless on beam.

It's an infrared beam.

Is the beam solid or hollow?

This is a powerful laser.

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

So this robot is actually equipped with a camera and a laser rangefinder, laser scanner.

Laser interferometer displacement sensors in J.G.

Nathan Myhrvold Could this laser zap malaria?

Don't point the laser at my face!

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.

On the Democratic side, the same sorts of hacks and PR men focused like a laser beam on the bad employment news of the George W. Bush years, ignoring the good news about output and productivity.

And we also use three laser range finders.

This beam won't hold the weight of the second story.

And I was writing software to visualize laser scanners.

The Russian goalkeeper was struck by a laser pointer.

My laser printer can only handle black and white.

Laser surgery can fix some kinds of vision problems.

A rotating cog wheel was placed in the path of the light beam as it traveled from the source, to the mirror and then returned to its origin.

Last year the government put on an impressive laser show.

It's illegal to shine a laser pointer at an airplane.

It's illegal to shine a laser pointer at an airplane.

My laser printer can only do black and white prints.

In this machine, a beam of protons and anti protons are accelerated to near the speed of light and brought together in a collision, producing a burst of pure energy.

E Spaceship noise SW Even if it doesn't have a laser?

E Laser noise SW Yeah, yeah. That was pretty funny, Einstein.

Green light... Red light!

A light bulb gives light.

Laser printers are generally less expensive to maintain than ink jet printers.

Laser printers are generally less expensive to maintain than ink jet printers.

In other words, the pump wavelength is shorter than the laser wavelength.

Light is quintessential. Light is life.

Balance beam and floor exercise where Biles is the defending world champion lay in wait.

Back scattered electrons (BSE) are beam electrons that are reflected from the sample by elastic scattering.

My brother in law seems interested in having laser eye surgery or tooth whitening.

The right signal twice then the left signal twice means that the car in front of you wants you to switch off the high beam and use low beam forward illumination instead, especially when on a highway.
