Need help with argument about wave equation

  1. May 6, 2013 #1
    in the equation v=f[tex] /lambda [/tex] can you use c instead of v for wavespeed?

    Hi Pseudo Epsilon! :smile:
    If c = v, yes.

    (ie electromagnetic waves in a vacuum)

    but ive heard it used for other things. Cant it EVER be used for non-em waves? Would it e incorect?

    It depends on whether or not you are using c to mean the speed of light in a vacuum. If you are then you can't use it as that isn't the speed of the wave. If you are using it as a general speed of a wave and not ##3 \times10^8## then you could use it in the same way as you could use any other symbol, however using c does risk confusion.
