photoelectric equation
1einstein's photoelectric equation — noun Usage: capitalized 1st E Etymology: after Albert Einstein : an equation in physics giving the kinetic energy of a photoelectron emitted from a metal as a result of the absorption of a radiation quantum: Ek=hν ω where Ek is the kinetic energy …
2Einstein's photoelectric equation — Physics. the equation that relates the energy of a photoelectron to the difference between the product of the frequency of the incident radiation times Planck s constant and the energy needed to remove the photoelectron from the substance. [named …
3photoelectric effect — Physics. the phenomenon in which the absorption of electromagnetic radiation, as light, of sufficiently high frequency by a surface, usually metallic, induces the emission of electrons from the surface. Also called photoemission. [1890 95] * * *… …
