Wavelength And Energy Of Waves

Infrared radiation

Infrared (IR) light is electromagnetic radiation with longer wavelengths than those of visible light, extending from the nominal red edge of the visible spectrum at 700 nanometers (nm) to 1 mm.

Visible light spectrum

The visible spectrum is the portion of the electromagnetic spectrum that is visible to (can be detected by) the human eye. Electromagnetic radiation in this range of wavelengths is called visible light or simply light.

Ultraviolet radiation

Ultraviolet Radiation(UV) is simply one form of energy coming from the sun. Even though you may have only just started hearing about UV and the effects it has on you, it is nothing new. In fact, UV is as old as the earth itself.

Visible light

is electromagnetic radiation that is visible to the human eye, and is responsible for the sense of sight.

Electromagnetic spectrum

the range of wavelengths or frequencies over which electromagnetic radiation extends.
