The photoelectric effect equation
Webb4 sep. 2024 · According to Albert Einstein, the photoelectric effect is explained as follows: Thus, hν = W + E Where • h represents Planck’s constant. • ν represents the frequency of the incident photon. • W represents a work function. • E represents the maximum kinetic energy of ejected electrons: 1/2 mv². History of Photoelectric Effect WebbIn 1905 Einstein extended Planck’s hypothesis to explain the photoelectric effect, which is the emission of electrons by a metal surface when it is irradiated by light or more …
