Cherenkov radiation is light emitted by a particle moving through a medium with a speed greater than the speed of light in the medium. (Note: The speed of the particle is not greater than the speed of light in a vacuum.) Consider a beam of electrons passing through water with an index of refraction of 1.33. If Cherenkov light is emitted, what is the minimum speed of the electrons?
