UV (ultraviolet) light from the sun is divided in to 3 categories UVA, UVB and UVC. Their wavelengths ranging between 100-400 nm. UVC light in the range of wavelengths between 100 and 280 nm is capable of inactivating microorganisms, such as pathogens,...

Research now suggests that UV light may have played a critical role in the emergence of life on Earth and could be a key for where to look for life elsewhere in the universe. UV light is a form of radiation that is classified into three primary types:...
