Define work function in photoelectric effect
WebAnswer. Part 1. Recall the formula for the maximum kinetic energy of a photoelectron, 𝐸 = ℎ 𝑓 − 𝑊, m a x where 𝑊 is the work function and ℎ 𝑓 is the photon energy value, which depends on … WebFeb 24, 2016 · 1 Answer. Sorted by: 1. Easily oxidizing atoms and ones with a low work function are correlated. In an atom that is easily oxidized, the valence electrons are very weakly bound to the nucleus of the atom for a number of reasons. In a large atom, the large number of electrons provides shielding from the nuclear charge.

Web6.2 Photoeffect. A photoelectric effect is the absorption of a gamma quantum by an electron, in which the gamma quantum gives up almost its entire energy to the electron. Absorption by a free electron is impossible, as the law of momentum conservation is not satisfied. Therefore, the photoelectric effect occurs on bound atomic electrons, and ... WebVerified by Toppr. When the light means photons incident on a metal surface, the electrons are emitting from metal surface, called photoelectric effect. The Einstein's Photo-Electric equation : KE max=hf−W. Here, KE max is the maximum kinetic energy of photo-electron, h is the Planck's constant, f is the frequency of incident light and W is ...
