Uv c carries the most energy capable of destroying the bonds that hold together the dna and rna of viruses and bacteria stopping them from working. Uv a has the longest wavelength of 320 400 nm and is responsible for 95 of the uv radiation that reaches. Ultraviolet uv light disinfection is getting a lot of attention during the coronavirus pandemic.

While they are similar each type of ray has a different wavelength and can penetrate surfaces to a certain extent. Its ability to kill pathogens like viruses and bacteria.
