Einstein photoelectric law Einstein photoelectric law[′īn‚stīn ¦fōd·ō·i¦lek·trik ‚lȯ] (quantum mechanics) The law that the energy of an electron emitted from a system in the photoelectric effect is h ν -W, where h is Planck's constant, ν is the frequency of the incident radiation, and W is the energy needed to remove the electron from the system; if h ν is less than W, no electrons are emitted. |
