WebAug 26, 2024 · E f = K m a x + ϕ. where K m a x is the kinetic energy, given by Equation 3.3.1, that an electron has at the very instant it gets detached from the surface. In this energy balance equation, ϕ is the energy needed to detach a photoelectron from the surface. This energy ϕ is called the work function of the metal.
WebThe existence of the cut-off frequency f c f c for the photoelectric effect follows from Equation 6.14 because the kinetic energy K max K max of the photoelectron can take only positive values. This means that there must be some threshold frequency for which the kinetic energy is zero, 0 = h f c − ϕ . 0 = h f c − ϕ . income tax valuation allowanceincome tax union budget 2023Web1/2mv 2max =h (v−v 0) V max is the maximum kinetic energy of the electron.
