Question

Does photoelectric effect support the wave nature of light

Answer 1

No i think .

it supports particle nature.

Answer 2

Solution :-

Particle nature of light can be verified by photoelectric experiment.

Let us suppose light to be a wave then, when it is incident on a metal surface and interact with electrons, it will take time to provide energy to the electrons and also, any intensity of the incident wave is able to provide sufficient energy to electrons (though less intensity waves might take time), so that electrons emit out of the metal surface.

But actually it doesn't happens,

The case is that there is negligible time lag between photon collisions with metal and photoelectron emission irrespective of intensity of incident light.(Incident light intensity should be greater than threshold frequency of the metal)

This proves that light show particle nature or, quantum nature.
