WebLight's particle-like traits are best explained by the photoelectric effect, the theory that Albert Einstein won his Nobel Prize for.. The photoelectric effect reffers to the emission (or ejection) of electrons from the surface of a metal in response to incident light. Energy contained by the incident light is absorbed by the electrons in the metal; this gives the … 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. ...
