| 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.

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.
