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 conservation of momentum ?

Explain photoelectric effect Explain the effect of increase of intensity of incident radiations on photoelectrons emitted by a photo-tube.

The stopping potential in an experiment on photoelectric effect is 2V. What is the maximum kinetic energy of the photoelectrons emitted ?

In a photoelectric effect , the K.E. of electrons emitted from the metal surface depends upon

The electrons are emitted in a photoelectric effect from a metal surface

Ligth emitted during the de excitation of electrons from n=3 to n=2, when incident on metal, photoelectrons following de excitations photoelectrons are just emitted from that metal. In which of the following de excitations photoelectric effect, is not possible ?
