phase velocity
The velocity of propagation of a uniform plane wave, given by (a) the product of the wavelength and the frequency divided by (b) the refractive index of the medium in which the wave is propagating. Note 1: In free space, the refractive index may be considered as unity. Note 2: In free space, the group velocity and the phase velocity are equal.
