Summary

Diagram of the photoelectric effect

This picture is incorrect! It shows three incoming photons, but only two outgoing electrons. There should be three outgoing electrons. This is the whole point of the photoelectric effect, and why Einstein got the Nobel prize for this: the correspondence between the number of incoming photons and the number of outgoing electrons is 1-1! Dohh!

I do not agree with the observation. The outgoing electrons are as a result of two photons which hit the metal earlier. The incoming photons are yet to strike the metal surface.HUHH!!

There should be 3 out going electrons. who makes this picture

Wavelength of incident light is not specified, nor assumed to be identical. One may infer that the wavelength/freq of one photon was insufficient to overcome the work function. This identical diagram has appeared in numerous published books on the subject

The photo electric effet depand on the frequency of the incident light,the photo cell emits photons only when the frequency of incident light is grater or equal to the therashold frequency (every element has its own therasold frequency).

Actually one of the photon is unable to eject an electron bcuz its frequency is below threshold frequency. the picture justifies the fact that all photons r unable to emit photoelectrons...only the ones with a frequency higher than threshold frequency does.

THIS Pic is incorrect
