Einstein's photoelectric effect equation
WebNov 13, 2024 · The minimum energy required to free an electron from the given surface is called the photoelectric work function (∅ o) of the material of the surface. The work … WebThe existence of the cut-off frequency f c f c for the photoelectric effect follows from Equation 6.14 because the kinetic energy K max K max of the photoelectron can take only positive values. This means that there must be some threshold frequency for which the kinetic energy is zero, 0 = h f c − ϕ . 0 = h f c − ϕ .
