Ultraviolet (UV) light is invisible radiation within a range of the solar spectrum. UV is similar to the wavelengths that are produced by visible light, but much shorter. UV radiation is measured in millionths of a millimeter, i.e., Angstrom units (one Angstrom unit wave-length equals one hundred-millionth of a centimeter), and like visible light, it primarily has a surface effect.
