Photoelectric current and frequency
The photons of a light beam have a characteristic energy, called photon energy, which is proportional to the frequency of the light. In the photoemission process, when an electron within some material absorbs the energy of a photon and acquires more energy than its binding energy, it is likely to be ejected. If the photon energy is too low, the electron is unable to escape the material. Since a…

WebJan 20, 2012 · 3.For a given metal of particular work function, increase in frequency of incident beam increases the intensity of the photoelectric current. 4.Above the threshold frequency, the maximum kinetic energy of the emitted photoelectron is independent of the intensity of the incident light but depends on the frequency of the incident light. Webphotoelectric effect, phenomenon in which charge particles are released from a material when it absorbs radiant energy. The photoelectric effect commonly is thought of as the ejection of electrons from the surface of a metal plate when light falls on it. In the broad sense, however, the phenomenon can take place when the radiant energy is in the region …
WebThe photoelectric effect is the emission of electrons when electromagnetic radiation, such as light, hits a material.Electrons emitted in this manner are called photoelectrons. The phenomenon is studied in condensed matter physics, and solid state and quantum chemistry to draw inferences about the properties of atoms, molecules and solids. The …
