Webphase velocity: [noun] the velocity of a wave motion as determined by the product of the wavelength and frequency — called also#R##N# wave velocity; compare group velocity, particle velocity. WebThe bottom graph is the addition of the top two graphs and you will note that a modulating envelope the peak of which as shown by the red dot travels at the group velocity where group refers to the motion of a number (group) of waves added together and $\left (\dfrac{dx}{dt}\right)_{\rm group} = \dfrac {\Delta\omega} {\Delta k}$.
