Photoelectric

The photoelectric effect occurs when light (or similar incident radiation, including X-rays) falls on material together with a metal plate and causes it to emit electrons. The discovery of the photoelectric effect led to important new theories (and to a Nobel Prize for Albert Einstein). Photoelectric cells, or photocells, are utilized in burglar-alarm light detectors and garage-door openers (each employs a through-beam of light this is broken when something movements throughout it), and also to play soundtracks on film movies (in which a light beam shines through the soundtrack encoded at the film and is "read" with the aid of the photocells).
