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.

Is visible light a form of electromagnetic radiation?
Yes, visible light is a form of electromagnetic radiation. It falls within the electromagnetic spectrum between ultraviolet and infrared radiation.
Which form of electromagnetic radiation has more energy than visible light waves have?
Ultraviolet (UV) radiation has more energy than visible light waves.
Does infred waves have the same wavelength as visible light waves?
No, infrared waves have longer wavelengths than visible light waves. Infrared waves have wavelengths ranging from about 700 nanometers to 1 millimeter, while visible light waves have wavelengths ranging from about 380 to 750 nanometers.
How is visible light and electromagnetic radiation different?
Visible light is a specific portion of the electromagnetic spectrum that humans can see with their eyes. Electromagnetic radiation, on the other hand, refers to all forms of energy that travel as waves at the speed of light, including visible light as well as other forms like radio waves, microwaves, and X-rays.
Do radio waves travel through vacuum fasetr than visible light waves?
No, radio waves and visible light waves both travel at the speed of light in a vacuum, which is approximately 299,792 kilometers per second. The speed of light is constant, regardless of the wavelength of the electromagnetic 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.
What is the type of electromagnetic radiation we can see called?
Visible light waves.
What is the type of electromagnetic radiation we can see?
Visible light waves.
How do flashlights emit radiation?
Flashlights emit radiation in the form of light waves through a process called incandescence, where a filament heats up and produces visible light. The light waves are a type of electromagnetic radiation within the visible spectrum.
What is the suns waves called?
The sun emits various types of waves, including electromagnetic radiation such as visible light, ultraviolet light, and infrared radiation. These waves are collectively referred to as solar radiation.
Is visible light a form of electromagnetic radiation?
Yes, visible light is a form of electromagnetic radiation. It falls within the electromagnetic spectrum between ultraviolet and infrared radiation.
Which form of electromagnetic radiation has more energy than visible light waves have?
Ultraviolet (UV) radiation has more energy than visible light waves.
What are the Electromagnetic waves between radio waves and visible light in frequency?
Terahertz and infrared radiation.
What type of energy has to do with light and radiation sent in waves?
Electromagnetic energy is the type of energy that has to do with light and radiation sent in waves. This energy includes visible light, radio waves, microwaves, infrared radiation, ultraviolet radiation, X-rays, and gamma rays.
How much of 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 is infrared in terms of physical science?
Light waves visible by thermal radiation.
What radiation that travels as waves?
The radiation that travels as waves includes electromagnetic radiation, such as visible light, radio waves, microwaves, and X-rays. These waves vary in frequency and energy, with higher frequencies corresponding to more energetic radiation.
