The photoelectric effect was first introduced by Wilhelm Ludwig Franz Hallwachs in the year 1887 and the experimental verification was done by Heinrich Rudolf Hertz. They observed that when a surface is exposed to electromagnetic radiation at a higher threshold frequency, the radiation is absorbed and the … See more The photoelectric effect cannot be explained by considering light as a wave. However, this phenomenon can be explained by the particle nature of light, in which light can be … See more The photoelectric effect is the process that involves the ejection or release of electrons from the surface of materials (generally a metal) when light falls on them. The photoelectric effect is an important concept … See more According to Einstein’s explanation of the photoelectric effect: The energy of photon = energy needed to remove an electron + kinetic energy of the … See more WebAnswer. The photoelectric effect refers to the emission, or ejection, of electrons from the surface of, generally, a metal in response to incident light. Energy contained within the incident light is absorbed by electrons within the metal, giving the electrons sufficient energy to be 'knocked' out of, that is, emitted from, the surface of the ...
WebPhotoelectric Effect. Sir J.J. Thomson, observed that when a light of certain frequency strikes the surface of a metal, electrons are ejected from the metal. This phenomenon is known asphotoelectric effect and the ejected electrons are called photoelectrons. A few metals, which are having low ionization energy like Cesium, show this effect ... WebIn the photoelectric effect, if the intensity of a light is shone on metal increases, what will happen? A.) ejected electrons will be faster B.)ejected electrons will be slower C.)there would be more electrons ejected D.)there would be fewer electrons ejected E.)no change .

WebApr 7, 2024 · In the photoelectric effect, the energy of the photon is consumed by the electron. While in the Compton effect, a photon is dissipated. A superior method to examine this is to understand that in the photoelectric impact, the electromagnetic wave couples two-electron states (bound and energized) by means of the recurrence contrast which those ... greatway bccWebJan 30, 2024 · Photoelectric Effect. To understand the principles of photoelectron spectroscopy, the photoelectric effect must be applied. The photoelectric effect states that electrons can be pushed off the surface of a solid by electromagnetic radiation. The ejected electrons are called photoelectrons. Figure 2.
