The Cherenkov effect A charged particle traveling in a dielectric medium with n>1 radiates Cherenkov radiation if its velocity is larger than the phase velocity of light v>c/n or Î² > 1/n (threshold) The emission is due to an asymmetric polarization of the medium in front and at the rear of the particle, giving rise to a varying electric dipole momentum.
