The effect was discovered in by Heinrich Hertz and explained by Albert Einstein in work for which he received the Nobel Prize photoelectric emission the release or absorption of quanta above a certain energy level photoelectrically in a photoelectrical manner, by emission of electrons from metals under electromagnetic radiation photoelectrically By means of photoelectricity photoelectrically by photoelectric means; “they measured it photoelectrically.
