It can not be explained by classical thermodynamics and statistical mechanics.
The Photoelectric Effect
1. The kinetic energy of the ejected electrons depends linearly on the frequency of the light.
2. There is a particular threshold frequency for each metal.
3. The increase of the intensity of the light results in the increase of the number of photoelectrons.
Classical physics:The energy of light wave should be directly proportional to intensity and not be affected by frequency.
The diffraction of electrons

should include a spin parameter in addition to its spatial coordinates. Each electron must have a unique set of quantum numbers.
