### Photoelectric Effect

If 1 million high energy photons hit a metal surface what is the maximum number of electrons that could be ejected from the metal surface? Would it be .5 milllion and if so why?

I think the maximum would be 1 million electrons, because there is a 1:1 ratio of photons to electrons in terms of energy. Each photon has enough energy to eject one electron and no more.

If 1 million high energy photons hit a metal surface, the maximum amount of electrons that could be ejected would be 1 million electrons, not .5 million. This is because the ratio of incoming photons to ejected electrons is 1:1, provided that each of the photons has a high enough energy to cause the release of an electron.
