Question

Write down Einstein’s photoelectric equation and explain the photoelectric effect on its basis

Answer 1

$\huge \purple A \purple N \purple s\purple W \purple e \purple \R :-$

When the light means photons incident on a metal surface, the electrons are emitting from metal surface, called photoelectric effect.

The Einstein's Photo-Electric equation : KEmax = hf−W

Here, KEmax

is the maximum kinetic energy of photo-electron, h is the Planck's constant, f is the frequency of incident light and W is the work function of the metal.
