The maximum kinetic energy \(\mathrm{KE}_{e}\) of ejected electrons (photoelectrons) is given by \(\mathrm{KE}_{e}=h f-\mathrm{BE}\), where \(hf\) is the photon energy and BE is the binding energy ... WebThe photoelectric effect is as follows: when electrons in a metal are exposed to light of sufficient radiation, the electrons are ejected from the metal surface. If we know the kinetic energy of the ejected electrons (known as photoelectrons ) and the energy of the incident radiation, we can calculate the energy of the electrons in the solid metal. how to save in picsart
