Photoelectric effect cannot be explained acoording to wave theory because of follwoing reasons:
1. According to wave theory, after the light falls on a substance electrons are emitted after a small instant of time. However, in photoelectric effect, the electron emissions are immediate without a time delay.
2. The energy of a wave increases with increase in intensity. However, in photoelectirc effect, increase in intensity has no effect on the energy of electrons emitted. All that happens is the number of electrons emitted, increases.
