Measuring Planck’s Constant Using the Photoelectric Effect
When a light of high enough frequency is shone on a metal, electrons are ejected from the metal. According to Einstein’s explanation, when a photon hits the metal, the electrons will be ejected from the metal with a range of kinetic energies from 0 J up to some maximum kinetic energy given by. where. Ek max is the maximum kinetic energy in J
