vip\r) = — ^— (31) Igrad g\ i>(p,(r) is called the phase velocity and is the speed
with which each of the cophasal surfaces advances. For a plane electromagnetic
wave one has from (28) that grad g = k, and therefore y(/» = ?U_^ because of (21)

The surfer's velocity is equal to the phase velocity in the case of ocean waves. (
The surfer is not moved forward by the wave; rather, the surfer slides down the
wave. If it were not for this sliding, only bobbing up and down would occur as the

Electromagnetic Noise and Quantum Optical Measurements
Hence, at large values of z, the propagation constant approaches fc, and the
phase velocity and group velocity approach c. On the other hand, for small values
of z the net phase delay is a linear function of z, giving the effective propagation ...

The propagation of a given constant value of phase QH defined by Q (.t, 0 = Q0
moves with the phase velocity cr(x,t) = dx/dt = a/k. The phase velocity cp(x,t) is
generally different for different values of Q,, and for different values of x and f .

Optical Interferometry
(3.13) In a nondispersive medium, dv/dλ = 0, and the group velocity is the same
as the phase velocity. However, in a dispersive medium, in which the phase
velocity depends on the frequency, the group velocity differs from the phase
velocity.
