WebThe photoelectric effect is as follows: when electrons in a metal are exposed to light of sufficient radiation, the electrons are ejected from the metal surface. If we know the kinetic energy of the ejected electrons (known as photoelectrons ) and the energy of the incident radiation, we can calculate the energy of the electrons in the solid metal. WebAug 26, 2024 · The photoelectric effect was explained in 1905 by A. Einstein. Einstein reasoned that if Planck’s hypothesis about energy quanta was correct for describing the energy exchange between electromagnetic radiation and cavity walls, it should also work to describe energy absorption from electromagnetic radiation by the surface of a …

WebMar 18, 2024 · The photoelectric effect is the process in which electromagnetic radiation ejects electrons from a material. Einstein proposed photons to be quanta of electromagnetic radiation having energy E = h ν is the frequency of the radiation. All electromagnetic radiation is composed of photons. WebPhotoelectric effect can only be explained by the quantum concept of radiation. 1) The photocurrent is proportional to the intensity of incident radiation. 2) The magnitude of stopping potential and hence the maximum kinetic energy of emitted photoelectrons is proportional to the frequency of emitted radiation. shantae game series order
