Ultraviolet radiation spans wavelengths from about 10 nm to 400 nm and is an important component of sunlight although the ozone layer prevents much of it from reaching the earth's surface. It is seperated in UV-A, UV-B and UV-C light. UV-C and UV-B light have a damaging effect on DNA and can therefore act as a desinfectant (killing microbes) or cause skin cancer and genetic mutation.
