Let P be the power of a point source of electromagnetic radiations, then intensity I at distance r from the source is given by. I = P/4πr 2 (W/m2) If A is the area of a metal surface on which radiations are incident, then the power received by the plate is. P' = IA = P/4πr2 (W)

Also from the experiment on Photoelectric effect, we see that there is a … 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
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 ...
