The system is composed of a Nd Yag laser, a light beam expander, a telescope, a CCD camera, a photo multiplier and a computer.

Electric fields are not ionizing radiation, like X rays or proton beams, that bombard tissue to disrupt DNA.

An enigmatic glimmer

Single crystals of BGO(Bi12GeO20), BSO(Bi12SiO20) and their solid solutions are wide band gap, high resistivity semi insulators that are also piezoelectric, photoconductive, acousto optic, magneto optic and optically active.

A drop of golden sun

Whenever a flash of light hits the receptor, the pore opens, an electrical current is switched on, and the neuron fires electrical impulses.

Your laser printer has a mirror galvanometer that's used to steer a laser beam very accurately that's what makes those little dots on the page.

The cable over there, that's an optical fiber.

Flashlights. Luminous dials for watches.

Happy hour signing off.

And keep that lighting on you.

Also, the atmosphere has a brightness all of its own, owing in part to scattering of electromagnetic radiation from various sources (such as city lighting, Moon light, auroral type phenomena and lightning).

The beam splitters and lenses are represented by physical objects, and the system projects down the laser beam path.

You see the red glow in their eyes, which is the reflection of the flashlight.

Then suddenly the happy times were finished.

You see those tiny blue beams.

Solar cells collect light for four and a half hours though.

One leads to the light, however, ends in an abyss.

So a ray of light could go down, be bent up into the observer's eye, and the observer sees a ray of light here.

This lamp sends out a powerful beam.

Light is converted to electricity on them.

This is a pulse of light that's only about one wavelength of light long, so it's a whole bunch of photons all coming and hitting simultaneously.

The electromagnetic force interacts with electrically charged matter via particles called photons.

And light is part of the electromagnetic spectrum.

We have a wonderful electric sign

It doesn't emit in the electromagnetic spectrum. It doesn't reflect.

This oh sorry, don't look at the beam. My fault.

We say, the ray of light came this way the galaxy must be there, OK.

If you put electricity on them, they emit light.

The petals track and the engine gets the concentrated sunlight, take that heat and turn it into electricity.

So long as the sun shines, we'll have no problem with power.

I compared the radio waves spectrum the size of it with the size of the visible light spectrum.

Glory, glory, halleluja Glory, glory, halleluja

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

And the animal's going to hear a tone and a flash of light occurred there.

Latin'radius' for'beam ', as it is radioactive

Greek'aktis' for'beam ' actinium is radioactive

Swing the beam to the left.

There are 10 billion electrical outlets in North America alone.
