towards us. Ultraviolet (UV) radiation is very similar to visible light, but the ultraviolet region starts right after the violet end, hence, ultra”violet” rays. The UV radiation from the sun can be very hazardous to humans and all other living organisms. High exposure to UV radiation can cause melanomas as the UV rays can affect living organism as the molecular level. It has a frequency of 10^(-8) Just like most forms of electromagnetic radiations, the main source of natural ultraviolet radiation...
