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.

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

Flashlights. Luminous dials for watches.

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

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).

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

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

Light is converted to electricity on them.

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

And light is part of the electromagnetic spectrum.

We have a wonderful electric sign

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

If you put electricity on them, they emit light.

There's massive P.V. arrays on the roofs as well as wind turbines.

There are 10 billion electrical outlets in North America alone.

The auroral zone is the quot mission target quot and the satellite carries energetic particle detectors, magnetic and electric wave experiments, electric field sensors and a UV imager.

We needed to beat solar cells.

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

And it's technological, so it can do things like microelectronics, and maybe photonics do.

Wind takes about two to five years on average, same as concentrated solar and photovoltaics.

Radio observatories also need to avoid spurious emissions (interference from television and radio stations, radar installations and car ignitions).

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.

It seems the lightning may snatch away their sight from them whenever it flashes they walk in it, and when it darkens they stand still if Allah willed, He could take away their hearing and their sight indeed Allah is Able to do all things.

the lightning wellnigh snatches away their sight whensoever it gives them light, they walk in it, and when the darkness is over them, they halt had God willed, He would have taken away their hearing and their sight. Truly, God is powerful over everything.

The lightning well nigh snatcheth away their sight whensoever it flasheth on them, they walk therein, and when it becometh dark unto them, they stand still. And had Allah willed He would of a surety have taken away their hearing and their sights verily Allah is over everything potent.

The lightning almost snatches away their sight, whenever it flashes for them, they walk therein, and when darkness covers them, they stand still. And if Allah willed, He could have taken away their hearing and their sight. Certainly, Allah has power over all things.

The lightning almost snatches their sight away. Whenever it illuminates for them, they walk in it but when it grows dark over them, they stand still. Had God willed, He could have taken away their hearing and their sight. God is capable of everything.

The lightning terrifies them as if it were going to snatch away their eyesight from them. When they see light, they move on a little further and When it becomes dark for them, they stand still. Had Allah so willed, He could have deprived them totally of their hearing and their sight. Most surely Allah has power over everything.

The lightning almost snatcheth away their sight from them. As often as it flasheth forth for them they walk therein, and when it darkeneth against them they stand still. If Allah willed, He could destroy their hearing and their sight. Lo! Allah is able to do all things.

The lightning almost snatches away their sight whenever it shines for them, they walk in it, and when the darkness falls upon them, they stand. Had Allah willed, He would have taken away their hearing and sight. Indeed Allah has power over all things.

The lightning almost snatches away their sight, whenever it flashes upon them they walk on, but as soon as it darkens they stand still. Indeed, if Allah willed, He could take away their sight and hearing. Allah has power over all things.

The lightning almost snatches away their sight. Every time it lights the way for them, they walk therein but when darkness comes over them, they stand still . And if Allah had willed, He could have taken away their hearing and their sight. Indeed, Allah is over all things competent.

The lightning almost takes away their vision. When the lightning brightens their surroundings, they walk and when it is dark, they stand still. Had God wanted, He could have taken away their hearing and their vision. God has power over all things.

The lightning almost takes away their sight whenever it shines on them they walk in it, and when it becomes dark to them they stand still and if Allah had pleased He would certainly have taken away their hearing and their sight surely Allah has power over all things.

The lightning almost takes away their sight whenever it flashes upon them, they walk on, but as soon as darkness falls around them, they stand still. Indeed, if God pleased, He could take away their hearing and their sight God has power over all things.

The lightning all but snatches away their sight every time the light (Helps) them, they walk therein, and when the darkness grows on them, they stand still. And if Allah willed, He could take away their faculty of hearing and seeing for Allah hath power over all things.

The auroral zone was the mission target and the satellite carried energetic particle detectors, magnetic and electric wave experiments, electric field sensors and a UV imager.

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.

The lights are turned on and off by the cloud, etc., etc., everything's done from the cloud.

Common elements include references to electrical, digital, magnetic, wireless, optical, electromagnetic, biometric and photonic technology, and references to the form in which information can be transmitted or stored (e.g. using telecommunications technology).

Well there are many molecules that exist in nature, which are able to convert light into electricity.
