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.

Hey friend here is your answer
photoelectric effect in which electrons were ejected when certain metals were exposed to a beam of light.
light of a particular frequency strikes a clean metal surface inside a vaccum chamber. electrons are ejected from the metal and are counted by a detector that measure the kinetic energy.
The electrons are ejected from the metal surface as soon as the beam of light Strike the surface i.e. there is no time lag between the striking of light beam and direction of electrons from the metal surface.
The number of electrons ejected is proportional to the intensity or brightness of light.
hope it help you ^_^
