phase speed
phase speed or phase velocityn (General Physics) physics the speed at which the phase of a wave is propagated, the product of the frequency times the wavelength. This is the quantity that is determined by methods using interference. In a dispersive medium it differs from the group speed. Also called: wave speed or wave velocity
