Albert Einstein discovered photoelectric effect and received the Nobel Prize in Physics for the same
PHOTOELECTRIC EFFECT:-
The photoelectric effect refers to the emission, or ejection, of electrons from the surface of, generally, a metal in response to incident light.
Energy contained within the incident light is absorbed by electrons within the metal, giving the electrons sufficient energy to be 'knocked' out of, that is, emitted from, the surface of the metal.
Using the classical Maxwell wave theory of light, the more intense the incident light the greater the energy with which the electrons should be ejected from the metal. That is, the average energy carried by an ejected (photoelectric) electron should increase with the intensity of the incident light.

Answer:
The phenomenon in which the absorption of electromagnetic radiation, as light, of sufficiently high frequency by a surface, usually metallic, induces the emission of electrons from the surface.
