Photoelectric effect

The photoelectric effect is the emission of electrons from a usually metallic surface upon exposure to, and absorption of, electromagnetic radiation, such as visible light or ultraviolet radiation. An older term for the photoelectric effect was the Hertz effect, though this phrase has fallen out of current use.http://scienceworld.wolfram.com/physics/HertzEffect.html
