The photoelectric effect is the emission of electrons from the surface of a conductor when light strikes it. Several important features of the photoelectric effect cannot be explained by the classical theory of electromagnetic waves. Briefly explain this phenomenon in terms of intensity, frequency, kinetic energy, and the number of photoelectrons.
