WebIn 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-energetic photons. The kinetic energy of the emitted electrons depends on the frequency ν of the radiation, not on its intensity; for a given metal, there is a threshold frequency ν0 below … WebIn Einstein’s approach, a beam of monochromatic light of frequency f is made of photons. A photon is a particle of light. Each photon moves at the speed of light and carries an energy quantum E f. A photon’s energy depends only on its frequency f. Explicitly, the energy of a photon is E f = h f 6.13 where h is Planck’s constant.
