Sound velocity

  1. Feb 11, 2013 #1
    I want to define (and find the sound velocity i iron).

    can i read it through the dispersion curves of iron?

    I am trying to see it through the group propagation velocity, vg = dw/dk, i. e the slope
    of the dispersion relation w(k).

    am i on the right track?





    thanks

    I am not sure what are you trying to do.
    For what purpose do you need the speed of sound in iron?
    For audio frequencies the dispersion is negligible and you can just look up the speed on a table.
