Conservation of momentum and conservation of energy imply that when a photon hits an electron on the surface of a metal with enough energy to eject it, the electron would conserve both the energy of momentum; however, if a photon has no mass - by which mv (momentum) and .5mv^2 (kinetic energy) equal 0 - where is that energy coming from? Does this have anything to do with the quantized energy of light?
