Define group velocity. show that group velocity of a wave packet equals the particle velocity.
Answers
The definition of group velocity is that any particle is totally equal to the total relativistic energy’s derivative with respect to the momentum that is relative.
The phase and group velocities are a function of the Compton and de.Broglie Wavelenghts of different particles.
Some people confuse group and phase velocities and use both the definitions interchangeably.
