Tag Archives: Cerenkov radiation

Light, usually bluish, emitted when a fast moving electrically charged automatic particle passes through a transport solid or liquid at a speed greater than that at which light travels in the solid or liquid. This radiation, named after the Russian physicist Pavl Alekseyevich Cerenkov who observed it in 1934, is the optical equivalent of the sonic boom emitted by supersonic aircraft, and can be used to detect electrically charged particles.
