Ultraviolet light is a type of electromagnetic radiation which comes from the sun.
Most UV-B and UV-C released is absorbed into the ozone layer. UV-A, due to its nature of being a much longer wavelength, is the majority of the UV passing into the atmosphere.
Named after the last visible light on the spectrum, at which point is no longer visible above.
Wavelength range between 10 nm to 400 nm.
Frequency range between 8 × 1014 to 3 × 1016 cycles per second; hertz (Hz)
Ultraviolet light is used for eliminating bacteria from the water supply.
Ultraviolet light can be used to modify chemical reactions through the photon's energy.
UV acts as a form of germicidal in order to kill pathogens.
According to the International Journal of Dermatology, UV light is a major cause of skin cancer.
Ultraviolet radiation (UVR) is the major etiologic agent in the development of skin cancers. UVR causes DNA damage and genetic mutations, which subsequently lead to skin cancer.
(International Journal of Dermatology)The same paper goes on to state that 132,000 new cases of melanoma occur worldwide each year, and the trend is much higher in Caucasians then their African Americans Hispanics counter parts.
