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 part of the light spectrum, which is classified into three wavelength ranges: 1  UV-C, from 100 nanometers (nm) to 280 nm.V-C light is germicidal â i.e., it deactivates the DNA of bacteria, viruses and other pathogens and thus destroys their ability to multiply and cause disease.
