Photoelectric equation
WebIn equation form, Einstein found the energy of a photon or photoelectron to be E = h f, E = h f, where E is the energy of a photon of frequency f and h is Planck’s constant. WebAnd Einstein’s Photoelectric equation is given by, K.E. = hν – Ø0. Where K.E. is the kinetic energy of the photoelectrons. Ø0 is the work function of the metal. hν is the energy of the photons. Photoelectric Effect. In 1887, Hertz noticed that electrons are emitted from a metal surface when electromagnetic radiation falls on it.
