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 ...

WebThe photoelectric effect was originally observed in 1939 and was documented by Heinrich Hertz in 1887. 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 ... 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
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 . Web11.6: In an experiment on the photoelectric effect, the slope of the cut-off voltage versus frequency of incident light is found to be 4.12 × 10-15 V s. Calculate the value of Planck’s constant. Solution: Given that the slope of cut-off voltage (V) versus frequency (v) being: V and frequency being related by the equation as: Hν = eV Where,
WebExperimental Study of Photoelectric Effect. The aim of the experiment is to study the emission of electrons by light. We also try and measure the energy of the electrons emitted in the process. In addition to this, we will also observe the relation of these electrons with the frequency of light used. To study the effect, we use an evacuated ...
