Photoelectric equation
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. WebThe photoelectric effect is the emission of electrons when electromagnetic radiation, such as light, hits a material. Electrons emitted in this manner are called photoelectrons. ... Even after experiments showed that Einstein's equations for the photoelectric effect were accurate, resistance to the idea of photons continued.
