Problem

GREPhysics.NET Official Solution

Quantum Mechanics $\Rightarrow$ }Photoelectric Effect

The quantity $W$ is also known as the work function, and it's the minimum amount of work that has to be done to free the electron from the electron sea. If one forgets whether it's the electron or photon that's being moved, then here's a useful mnemonic. Remember that the photoelectric effect has a photon knocking out an electron and the Compton effect has an electron knocking a photon off course. (For the full fight-club analogy, See Prob 32)
