I know that there are specific equations that you can only use for an electron or something with mass. Which equation would you use to find the frequency of an electron?

For an electron, you would most likely be given info to complete the equation E - work function = KE to find the frequency.

De Broglie's equation is used with things that have mass (i.e. electrons). The photoelectric effect includes three components. E=hv is used ONLY for photons/light. The threshold equation is the energy needed to eject an electron and that is usually a given value. The kinetic energy of the electron is found by the equation E = (1/2)mv^2.
