The photoelectric effect is the emission of electrons or other free carriers when lightshines on a material.
DETAILED EXPLAINATION
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=hνE=hν is the frequency of the radiation. All electromagnetic radiation is composed of photons. As Einstein explained, all characteristics of the photoelectric effect are due to the interaction of individual photons with individual electrons. The maximum kinetic energy KEeKEe of ejected electrons (photoelectrons) is given by KEe=hν–ΦKEe=hν–Φ, where hνhν is the photon energy and ΦΦ is the workfunction (or binding energy) of the electron to the particular material.
