Phase/group velocity

  1. Nov 9, 2004 #1
    Can anyone help me with this?

    If w = square root of (gk) what is the phase and group velocity and show that the group velocity = v/2.

    It's [tex] v_{g} =: \frac{d\omega(k)}{dk} [/tex],where the [tex] \omega(k) [/tex] is the dispersion relation.
