Webb12 sep. 2024 · The photoelectric effect has three important characteristics that cannot be explained by classical physics: (1) the absence of a lag time, (2) the independence of the kinetic energy of photoelectrons on the intensity of incident radiation, and (3) the presence of a cut-off frequency. Let’s examine each of these characteristics. Webb6 apr. 2024 · Precisely the energy of the photons goes to the electrons which are present in the material. As a result, the electrons get excited, and they start jumping to the higher energy state, which is known as the conduction band. Once the electrons are jumping to the conduction band, they leave behind holes in the valence band.

Webb13 okt. 2024 · The photoelectric effect occurs when electrons are released after light is shone onto a metal. Electrons released in this way are called photoelectrons, which leads to the name photoelectric effect. WebbIn the photoelectric effect, the electromagnetic wave is thought to exist as quanta (discrete packets) of energy, called photons. When an EM wave is directed at a metal surface, the photons are absorbed by the electrons, causing them to be emitted from the surface. This will only happen if the photon has greater energy than the work function ...
