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.
The frequency range of visible light.
No, x-rays are not visible light.
Visible light. It has a higher frequency so more energy.
The (not surprising) name is "visible light."
Visible light is made of rays. There are rays with wavelengths that are shorter than visible light and other with longer wavelength.
light (electromagnetic radiation of a wavelength that is visible to the human eye (about 400–700 nm))
this question can not be answered not even through science facts sorry
One difference between visible and non-visible light is that visible light can be seen by the human eye, while non-visible light, such as ultraviolet or infrared light, cannot be seen without special equipment.
The answer is visible light. Visible light is light that can be seen with a naked eye
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.
No, ultraviolet light is not visible to the human eye. It has a shorter wavelength than visible light, which makes it invisible.
Yes. visible light is in the electromagnetic spectrum.
exactly what you said its called visible light.
The frequency range of visible light.
No, x-rays are not visible light.
In the given scenario, light is visible.
Visible light. It has a higher frequency so more energy.
