RICH detectors use this effect to measure the velocity of subatomic particles.
RICH detectors use this effect to measure the velocity of subatomic particles. In a periodic medium, such as the surface of a diffraction grating, this effect requires no minimum velocity. Its spectral intensity is approximately proportional to the frequency, according to the (*) Frank-Tamm formula, so most of its energy is actually in the UV. Observatories such as IceCube and Super-Kamiokande use this effect to detect neutrinos. Created when a particle travels through a medium faster than the local speed of light, for ten points name of this type of radiation characterized by a blue glow in nuclear reactors.
