Hi there,
IÕm in a graduate tree physiology course and I ran into a question that no
one
had an answer to. We had a brief refresher on photosynthesis (at a very
basic
level), and while we were discussing how the energy of photons was
transferred, I remembered something about a controversy as to whether or
not a photon contained mass. So my question is: Does a photon have mass or
is
it just an energy wave?
Thanks for any answers I get.
