Dear student,

Photoelectric effect is a phenomenon based on the particulate nature of EM radiation.
When the photons of energy greater than the work function function of the metal falls on it, electrons are emitted from the metal with energy maximum upto difference in incident energy of photons and the work function of metal. This relation can be written mathematically to obtain the photoelectric equation-


whereis the work function of the metal.
