Main Question or Discussion Point
Ultraviolet light can kill skin cells but infrared light only warms skin cells even though both types of lights are from the sun. Why is this, explain using the photon theory...?
Uhm... When you say mutations in skin cells, you mean what exactly? Moles are thought to be in part caused by damage to DNA brought on by UV radiation, and can be precursors to melanomas.Moles are mutations in skin cells...not genes though. Gamma rays can mutate DNA strands.
