Ultraviolet (UV) Spectrum

The wavelength interval of the electromagnetic spectrum that corresponds to ultraviolet light (light that is beyond the visible violet range). UV radiation is often divided into three smaller regions: 320 - 400nm, 280 - 320nm, and 100 - 280nm – defined as UV-A, UV-B, and UV-C, respectively.
