Question

What is meant by wave packet ? Differentiate between the phase velocity and the group velocity?

Answer 1

In other words, the velocity of the particle is equal to the group of the waves with which the wave packet is made of. The velocity of the group or wave packet is called the group velocity. The group velocity can be mathematically expressed as, vg = Dω/dk. It is the velocity with which the particle moves.Apr 15, 2016
