The Askaryan effect can generate this phenomenon, whose alteration by a periodic grating is the Smith-Purcell effect. Hankel functions were utilized by Ilya Frank and Igor Tamm to develop a formula calculating the intensity of this effect. It occurs when an electromagnetic field in a local medium is disrupted, releasing photons that constructively interfere and is often considered an analogue of a sonic boom. For 10 points, name this effect named for its Russian discoverer which occurs when particles propagate faster than the local speed of lig

It occurs when an electromagnetic field in a local medium is disrupted, releasing photons that constructively interfere and is often considered an analogue of a sonic boom. For 10 points, name this effect named for its Russian discoverer which occurs when particles propagate faster than the local speed of light through a medium, generating an oft-seen blue color.
