Main Question or Discussion Point

It is said that photoelectric effect of light proves that light has particle nature, but which property is shown by light in the photoelectric effect which is also the property show by things having particle nature? Even in the photoelectric effect the energy is transferred in the form of wave not by direct collision (The last part can be wrong).

Yes. It only really proves that the energy appears in quanta. Steer clear of the particle idea unless you are prepared to go the whole way and chuck the little bullet model.
