Light is a form of electromagnetic energy. Visible light ranges through all the colors of the rainbow - red, orange, yellow, green, blue and violet. Light is generally considered to be those wavelengths and also some wavelengths just below red (infrared or IR) and just above violet (ultraviolet or UV). Light has an energy associated with it, and the lowest energy light is at what is called the lower end of the spectrum, which is the red end. The higher energy light is at the higher end of the visible spectrum, the purple (or violet) end. Higher energy light has a higher frequency and a shorter wavelength than lower energy, which has a lower frequency and a longer wavelength. Light, because it is electromagnetic energy, is different from mechanical energy, like sound (which is mechanical energy). Light can travel through a vacuum. The speed of light in a vacuum is a constant, no matter what frame of reference the observer has, and that is exactly 299,792,458 meters per second (about 186,282.397 miles per second). A link is provided to the Wikipedia article on light in case you wish to do some additional reading. And there is always WikiAnswers for more questions.
It is part of the electromagnetic spectrum.
It has the characteristics of a wave and a particle.
The photon is the force carrier.
It travels about 300,000 kilometers per second.
It can be refracted, reflected or absorbed.
It's energy is used in photosynthesis and in our eyes.
It has pressure, this can be increased to make lasers, etc.
The SI unit of measure is the candela.

What do the visible colars of light represent?
The frequency range of visible light.
Are X-rays visible light?
No, x-rays are not visible light.
Does a prism separate light into only the visible spectrum or the entire spectrum?
Well, seeing as it seperates visible light, it follows that it only seperates that visible light into the visible spectrum. You can't make radiowaves or UV rays out of visible light.
What is the definition of visible light waves?
EM rays which are in the range of visible light.
How do plants use visible light in photosynthesis?
photosynthesis uses the sun , which is a base point of visible light. all visible light starts at the sun ; therefore , photosynthesis uses visible in that manner.
What are facts on light?
light (electromagnetic radiation of a wavelength that is visible to the human eye (about 400–700 nm))
How does light make us visible?
this question can not be answered not even through science facts sorry
Which type of rays are visible?
visible light is the only VISIBLE light.
What kind of light is normal light that you use?
The answer is visible light. Visible light is light that can be seen with a naked eye
What is difference between visible and infrared light?
Visible light is visible (for the human eye), infrared is not. Infrared has a longer wavelength, and a higher frequency. visible light is visible to human i.e the VIBGYOR, above vibgyor are ultravoilet light which is not visible to human eye and below vibgyor are infrared light which is also not visible to human eye.
Is visible light electromagnetic?
Yes. visible light is in the electromagnetic spectrum.
What are Visible light waves?
exactly what you said its called visible light.
What do the visible colars of light represent?
The frequency range of visible light.
Are X-rays visible light?
No, x-rays are not visible light.
What are some false facts about light pollution?
Some FALSE facts on light pollution are: 1. Astronomers benefit from light pollution as it helps them to study stars. 2. All stars are visible in the night sky when viewed from a light polluted city. 3. Light pollution is good for the environment. 4. Light pollution doesn't affect human sleep cycles.
Does a prism separate light into only the visible spectrum or the entire spectrum?
Well, seeing as it seperates visible light, it follows that it only seperates that visible light into the visible spectrum. You can't make radiowaves or UV rays out of visible light.
What is the light called that the retina can detect?
"visible light." it has a shorter wavelength than other light types. "visible light." it has a shorter wavelength than other light types.
