WebLight consists of packets of energy called photons. The Plank-Einstein relation E = hν gives the energy of a photon beam of wavelength ‘ν’. If the frequency of the photons is greater than a specific value known as the … 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

WebAccording to the Einstein-Plank relation, we have E = hν …. (1) Where ‘h’ is the Plank’s constant and ‘ν’ is the frequency of the radiation emitted. Also from the experiment on Photoelectric effect, we see that there is a … WebJan 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.

Initially, it was termed as the Hertz effect but later it was called the photoelectric effect. In 1880 Hertz and Lenard observed that when a clean metallic surface is irradiated by monochromatic light of proper frequency, electrons are emitted ... WebKey terms related to Phototransistor.
