Wave Power

  1. Apr 2, 2008 #1
    So in my book, it derives the expression for power in a travelling transverse mechanical wave.

    P= Sqrt[(mu)F].(omega)^2.(A)^2

    It reduces this from: P=k^2.omega^2.F.A^2.(sin(kx-omega.t)^2

    Where all symbols are the standard ones in dealing with waves.

    Could someone please go thru how it got from 2 to 1? I can't see the logic. I'm sure its obviously just basic math I am overlooking, but there may be a misprint in the derivation.

    Can you fix the equation in your threadd? I can't read the problem, sorry.
