The photoelectric effect is a phenomenon in which electrons are ejected from a material’s surface when it is exposed to light (usually ultraviolet or higher frequency). The effect cannot be explained by classical wave theory but is consistent with the particle-like behavior of light proposed by Albert Einstein, who described light as quanta of energy called photons.
