Question

which nature of light supports photoelectric effect​

Answer 1

Explanation:

For in.stance, the photoelectric phenomenon is explained by using particle nature or quantum nature of light. Photoelectric effect cannot be explained on the basis of wave nature because experimentally we know that we need a parti.cular energy called the work function of the metal surface.

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.
