text: We all know Einstein's rather famous mass-energy equivalence, E=mc², and it's fairly obvious that photons have energy, so they must have mass, right?
text: The photon is the particle that produces and holds energy, and is responsible for the electromagnetic force.
text: Photons do carry energy and momentum, however, and, in transmitting these properties between particles, they produce the effects known as electromagnetism.
text: The energies involved in a nucleus are orders of magnitude greater than those for the electrons around the nucleus, so the photon has much more energy and we label it gamma radiation.
text: Well, the two photons are similar so they will have the same energy, and since energy is conserved the total final energy will be the same as the total initial energy, so
text: The photons will both have some energy; how much exactly?
