(3). $\space$ In the classical theory, the light energy is uniformly distributed over the wave front. Webb20 feb. 2024 · These make use of the photoelectric effect to convert light into electricity for running different devices. Figure 29.2. 1: The photoelectric effect can be observed by allowing light to fall on the metal plate in this evacuated tube. Electrons ejected by the light are collected on the collector wire and measured as a current.
