Question

What is the difference between phase velocity and group velocity.

Answer 1

Answer:

Briefly, phase velocity refers to the velocity of a monochromatic wave, let's say, the velocity of one of the peaks of the wave. ... On the other hand, group velocity refers to a group composed of waves within a frequency band ∆ω. Group velocity is the velocity with which the entire group of waves would travel.

Answer 2

Answer:

briefly,phase velocity referred to the velocity of a monochromatic wave, let's say the velocity of one of the peaks of the wave...... on the other hand group velocity referred to a group composed of waves within a frequency band. group velocity is the velocity with which the entire group of waves waves travel.
