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.
