In the photoelectric experiments the photocurrent is proportional to the intensity of the light.Can this result alone be used to distinguish between the classical and quantum theories?
As I know, this feature of photoelectric effect is the only feture that is compatible with classical concepts.So,this cannot be used like that...
[Classical Idea: As you increase the intensity of the light,you are treating the free surface electrons with Electric field and magnetic field of bigger amplitude---Force on them is bigger and they can speed up more promptly giving a bigger value of photoelectric current.]
