Does Oxygen molecules stop UV radiation or is it only Ozone molecules that can?
UV is commonly broken up into three rough groupings called UV-A, UV-B, and UV-C. Oxygen and nitrogen absorb UV-C and break apart. Some of the oxygen forms ozone. Ozone absorbs UV-C and some UV-B and breaks apart. Ozone also absorbs UV-B and reradiates it randomly. UV-A (the sutff good for tanning) is pretty much just passed thru to the surface of the Earth. So some UV is blocked by oxygen (UV-C), just not any of UV-B, which directly strikes our DNA since we are largely transparent to UV-B and DNA is not.
Which are more energetic photons of UV-A radiation or photons of UV-B radiation?
UV-B.
