Cerenkov, Pavel Alekseevich (1904–1990)
Russian physicist who, while working at the Institute of Physics of the
Soviet Academy of Sciences, discovered that light
is emitted by charged particles traveling through media at speeds higher
than the speed of light in those media.
This type of light is now known as Cerenkov
radiation. Cerenkov was awarded the 1958 Nobel Prize in Physics with
his co-workers, the Russian physicists I. M. Frank and I. Y. Tamm.
