GROUP VELOCITY:-

When a number of waves of slightly different wavelengths and velocities travel together in a medium the observed velocity of this group of waves is called the Group velocity. Such a group of waves is called a wave packet.

PHASE VELOCITY:-

The velocity with which a wave travels …
