Explained partially by Frank and Tamm, this phenomenon analogous to a sonic boom in sound waves involves constructive interference of the photons when a charged particle travels faster than the speed of light in a medium.
It is not normally observed because photons emitted by charged particles destructively interfere, but even when it occurs it usually is not visible because its emission mainly falls in the ultraviolet spectrum.

For 10 points, name this type of radiation that explains the blue glow of a nuclear reaction, named for the Soviet who won the 1958 Nobel Prize in physics.
