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

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

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

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

Olafur Eliasson Playing with space and light

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.

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

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.

This lamp sends out a powerful beam.

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

Light is converted to electricity on them.

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

In this example, each electrical impulse, each deflection on the trace, is caused by a brief pulse of light.

And light is part of the electromagnetic spectrum.

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.

So to explain that if you've got an elementary particle and you shine a light on it, then the photon of light has momentum, which knocks the particle, so you don't know where it was before you looked at it.

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.

If you put electricity on them, they emit light.

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.

There are 10 billion electrical outlets in North America alone.

Verily the lightning could snatch away their eyes. When it flashes forth they walk in its flare. When darkness returns they stand still. And if the Lord wills so He could take away their hearing and sight surely God is all powerful.

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

Now that we have concentrated sunlight, what are we going to put at the center to convert sunlight to electricity?

We needed to beat solar cells.

For every head is bald, and every beard clipped on all the hands are cuttings, and on the waist sackcloth.
