Question

In an experiment on photoelectric effect, a photon is incident on an electron from one direction and the photoelectron is emitted almost in the opposite direction. Does this violate the principle of conservation of momentum?

Solution

No, it does not violate the principle of conservation of momentum. In the photon-electron collision, the energy and momentum are conserved.

Q. When stopping potential is applied in an experiment on photoelectric effect, no photoelectric is observed. This means that
(a) the emission of photoelectrons is stopped
(b) the photoelectrons are emitted but are re-absorbed
