'''Ultraviolet''' (or '''UV''') is [[electromagnetic radiation]] in the wavelength range of 4 to 400 nanometers, shorter wavelengths than that of visible light. The [[sun]] produces UV, which is commonly split into three bands: [[UVA]],[[UVB]], and [[UVC]].

UVA is not absorbed by [[ozone]]. UVB is mostly absorbed by ozone, although some reaches the Earth. UVC is completely absorbed by ozone and normal [[oxygen]].
