For ordinary purposes, there are two common light mechanisms, Black Body and Spectral Line.
Black body radiation is the kind given off by a heated material - first a dull red glow, followed by red, orange and so on as the heating continues till it reaches white hot (and beyond).
Our incandescent filament light bulb is an example of this.
Spectral lines are given off when a material is energized and an electron jumps from its usual energy level to a higher one. When the material cools enough to allow the electron to drop down to its normal state, it emits a set of spectral lines. These are quite indicative of the element and its energy level. It is this technique that allows us to determine the spectral composition of distant stars, and hence their elemental composition.
LED lights, and similar solid state devices are of this class. As also are more esoteric sources such as the plasma seen in advertising signs.

Does infred waves have the same wavelength as visible light waves?
Infrared radiation is not visible. Its wavelength is longer than red.
Which form of electromagnetic radiation has more energy than visible light waves have?
Ultraviolet (UV) radiation has more energy than visible light waves.
Is visible light a form of electromagnetic radiation?
Yes. Radio waves, microwaves, visible light, and x rays are all examples of electromagnetic waves.
How much of the radiation from visible light waves is absorbed as the radiation passes through the atmosphere?
almost none the vast majority of visible light passes through the atmosphere.
What are the categories of the electromagnetic spectrum?
Long waves, medium waves, Short waves coming under Radio waves. Microwaves Infra red Visible light Ultra violet X-radiation Gamma radiation
What type of radiation is the sun a source of?
The Sun is a source of all forms of electromagnetic radiation from gamma rays to radio waves. However, the greatest amount of radiation that the Sun produces is visible light.
