It is stated that the experimental result from photoelectric effect that
The max. Kinetic Energy of the photoelectrons after the emission from the surface depends upon the frequency of the incident light.The max. KE increases with increasing frequency.
First of all, what was the prediction of the classical electromagnetic theory ? And secondly, in exactly which point that this contradicted with that wave theory of light ?
I mean the energy transferred by a wave is proportional with its frequency square, so if we increase the frequency, it can deliver more energy per unit time. I must also ask that how does the classical theory expects electrons's to have a KE after the emission ? I mean after the emission will the electron still absorb light during its movement to anode according to the classical wave theory of light ?
