But can UV cause heat as secondary process ?
. How does light, infrared and UV radiation interact with skin and eyes?
Heat is generated in the infrared (IR) part of the light spectrum, at the opposite end of the spectrum from ultraviolet (UV). Then when you get into the radio part of the spectrum, heat is generated by microwaves, but in a different way from the heat generated in the IR. IR actually carries heat with it, but microwaves generate heat at impact, by exciting water molecules to move more.
Ozone is transparent to IR, and transparent to the less destructive wavelengths of UV. The less destructive wavelengths of UV are also what stimulate human skin to produce melanin, and makes people tan.
