Ultraviolet light is a form of radiation which is not visible to the human eye. It's in an invisible part of the electromagnetic spectrum. Radiated energy, or radiation, is given off by many objects: a light bulb, a crackling fire, and stars are some examples of objects which emit radiation. The type of radiation being emitted depends on the temperature of the object.

Ultraviolet light is the light between X-Rays and Visible Infrared on the light spectrum, with wavelengths between 100 nanometers and 400 nanometers.
