What Is Meant By Group Velocity. The main difference between phase velocity and group velocity is that phase velocity is greater than the group velocity in a normal medium. The phase velocity is not the velocity at which “stuff” is transmitted by the wave. Group velocity is a concept used in physics to describe the speed at which a wave packet or a group of waves propagates through. Information may be conveyed as meaningful. This article tries to differentiate those differences in detail. We shall find that the speed of motion of wave packets, referred to as the group velocity, is given by \[u=\left.\frac{d \omega}{d k}\right|_{k=k_{0}} \quad \text { (group velocity). Group velocity can be interpreted as the speed at which a disturbance in the wave propagates. Waves can be in a group and such groups are called wave packets, so the velocity with which a wave packet travels is called group velocity. The velocity of the stuff is called the group velocity.
