There are three wavelengths of Ultraviolet light (UV light):
UVA (315-400 nm) – UVA has the longest wavelength as compared to the other types of UV and contributes to a number of health issues such as sunburn, skin aging, eye damage, skin cancer, and suppression of the immune system.
UVB (280-325 nm) – UVB is intermediate in wavelength and is involved in sunburn, snow blindness, immune system suppression, skin cancer, and premature aging.
UVC (180-280 nm) – UVC has the shortest wavelength and is frequently used in germicidal lamps to destroy bacteria and other organisms. It is harmful to the skin because it damages nucleic acid in cells.
UV light is used in tanning salons.
