Cherenkov radiation

…It was predicted by Soviet PA Cherenkov in 1934, and theoretically confirmed by I. Tamm and I. Frank in 1937. Light is emitted only in the frequency range where the particle velocity v is greater than the phase velocity of light in the medium (the speed of light c in a vacuum divided by the refractive index n of the medium), and this radiation is called Cherenkov radiation. The pale light seen near the fuel rods of a nuclear reactor underwater is an example of this radiation. …
