Phase Velocity
</dt>
Of a traveling
plane wave at a single frequency,
the velocity of an equiphase surface along the wave normal. Also called
phase 'speed, wave speed, wave velocity.
</dd>
Thus, the component sin ( 2π/λ)(x - ct) represents a wavelength λ traveling in the positive x- direction with
phase velocity c. This concept is to be distinguished from signal velocity,
group velocity, and the velocity of fluid parcels. See velocity
of propagation.
