DescriptionPhase-and-group-velocity.png	English: Frequency dispersion of surface gravity waves on deep water. The red square moves with the phase velocity, and the green circles propagate with the group velocity. In this deep-water case, the phase velocity is twice the group velocity. The red square overtakes two green circles, when moving from the left to the right of the figure.
