Question

During a collision between a photon and an electron there is conservation of

Answer 1

Show that a photon cannot transfer all of its energy to a free electron. whre pe is the momentum of the electron after the collision. If K is the kinetic energy of the electron after the collision, and m0 is its rest mass, then conservation of energy implies, hf + m0c2 = m0c2 + K K = hf = hc λ = pec.

Answer 2

Show that a photon cannot transfer all of its energy to a free electron. whre pe is the momentum of the electron after the collision. If K is the kinetic energy of the electron after the collision, and m0 is its rest mass, then conservation of energy implies, hf + m0c2 = m0c2 + K K = hf = hc λ = pec,
