Cutoff frequency formula photoelectric effect
WebPhotoelectric effect equation The minimum amount of energy required by an electron to eject from the metal surface is called work function. It is denoted by Φ, thus Work function formula Φ=hν 0 Where ν 0 is the threshold frequency. When a photon of energy hν falls on a metal surface, it transfers all its kinetic energy to the electron of the metal. WebApr 28, 2024 · The photoelectric effect is a one photon-one electron phenomenon. One photon cannot eject more than one photo-electron. Characteristics: For a given photosensitive material, there exists a certain minimum cut-off frequency of the incident radiation, called threshold frequency v 0 below which no emission of photoelectrons …
