WebAs light slams into the pie electron it is acting as a particle much like slamming marbles together. The KE of the photon is transfered to the pi electron causing it to jump to a higher energy state, thus ONE photon of light for ONE pie electron of the bond. WebMolecules can be unaffected or spun around, their bonds can be stretched, they can re±ect or absorb light, or they can be broken down by the light. Greenhouse gases interact with EM waves from the Sun and from Earth. Some forms of light are harsher than others on our ozone particles.
