[edit] 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

Wave length of incident light is not specified, nor assumed to be identical. One may infer that the wave length/freq of one photon was insufficent to overcome the work function. This identical diagram has appeared in numerous published books on the subjec

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).
