### Work Function

In Lavelle's lecture, I was confused on what the work function is. Can someone help clarify what it is and how to solve for it?

The work function is the minimum amount of energy a photon needs to have in order to eject an electron. In other words, it is the threshold energy. You can solve this by the equation E(photon) - work function = E(excess/KE).

### Re: Work Function

The work function is the amount of energy needed to remove an electron from a metal. Different metals have different work functions. It can also be denoted as threshold energy, or "energy removed e-." It is in the function, E(photon)-work function=Ek(e-)
