This shows that, apart from an overall phase factor, the pulse travels along
undistorted in shape with a velocity, called the group velocity: do * = I. o (7.32) If
an energy density is associated with the magnitude of the wave (or its absolute
square) ...

But a particle moving with constant velocity through a material medium can
radiate if its velocity is greater than the phase velocity of light in the medium.
Such radiation is called Cherenkov radiation, after its discoverer, P. A. Cherenkov
(1937).
