Homework Help: Visualizing group and phase velocity of a wave

  1. Nov 20, 2015 #1
    1. The problem statement, all variables and given/known data
    how to visualize group velocity and phase velocity?
    I tried to to visualize it
    The velocity of up and down vibration
    Of the wave as phase velocity.
    The velocity of the whole wave in propagating direction as group velocity.

    2. Relevant equations

    3. The attempt at a solution

    See the first animated figure here https://en.wikipedia.org/wiki/Phase_velocity and then see if you can describe in words the meaning of the phase velocity.
