| photoelectric | <physics> Acting by the operation of both light and electricity. Said of apparatus for producing pictures by electric light or electronic effects produced by the action of light. See: photoelectric effect, photoelectric absorption. (21 Jun 2000) |

| photoelectric absorption | <chemistry, physics> The interaction of an X-ray photon with matter in which the incident photon is completely absorbed, giving up all its energy by displacing an outer shell electron. (05 Mar 2000) |
| photoelectric effect | <chemistry, radiobiology> The interaction of a photon with an atom, resulting in the absorption of the incident photon and the release of a bound electron from that atom with energy equal to the photon energy less the electron binding energy. (16 Dec 1997) |

| photoelectric effect |
Experiment concerning the detection of electrons from a metal surface, whose speed off the surface was dependent on the frequency of light striking the surface. The theoretical explanation rests on viewing light as made up of photons, or individual bullets of energy.

| photoelectric effect |
The photoelectric effect is a phenomenon in which electrons are ejected from a the surface of a metal when light shines on the metal. Albert Einstein explined the photoelectric effect in 1921. PHOTOEVAPORATION Photoevaporation is a phenomenon in which the intense light from hot stars causes gases to evaporate (boil away) into interstellar space. In the Eagle Nebula (pictured above), ultraviolet light boils off some of the hydrogen gas (H 2 ), continually re-shaping the columns of the nebula.
