Question

Name various types of UV radiations depending upon their wavelength. What is their effect on humans?

Answer 1

UV-C is 100–280 nm, UV-B is 280–320 nm and UV-A is 320–400 nm. Ultraviolet exposure can damage living tissues and cause skin cancer, cataracts and weakening of the immune system; most UV-C and much UV-B are absorbed by ozone.
