Abstract
For many years the photoelectric effect has been taken to provide evidence for the quantum nature of electromagnetic radiation. However, as has been pointed out from time to time[1–3], if the electromagnetic field is treated as a classical, c-number perturbation acting on the bound electron, essentially the same conclusions can be reached as by quantum electrodynamics. For example, photoemission takes place only when the frequency ω is high enough for ℏω to exceed the work function W of the electrons,
and the probability of photoemission at time t is proportional to the expectation value of the light intensity I(t) at time t,
