Phase velocity/propagation velocity?

  1. Nov 25, 2007 #1
    what is the difference between the two, if any?

    In particular, I'm working on this transmission line problem where I'm given the time delay and the length. I can solve to find some sort of velocity--is it the phase velocity, or propagation velocity?

    I also have the equation lambda = vp * T. Again, is this phase velocity or propagation velocity?

    Thanks,
    Sean

    Sounds like Velocity of Propagation...not sure though.

    Lambda = v*T = v/f

    where,

    v = velocity of propagation
    T = period
    f = frequency

    Also, remember that c = f*lambda for free space (which is normally assumed for some applications).
