Homework Help: Standing Wave

  1. Apr 17, 2007 #1
    In a standing wave, if the fundamental frequency is 25hz
    but the frequency that is currently being fed to the string is 50hz how do i determine what the resulting wave will look like?

    Which harmonic of 25Hz is 50Hz?

    Is it the second one?

    Yes. So if the first mode of the fundamental has a half wavelength oscillation in the standing wave, how many wavelengths will there be for a 2nd harmonic standing wave oscillation?

    What about for fundamental frequencies that aren't multiples of 50hz.
    How do i calculate what waves would be created?

    Edit:nevermind this post, too early in the morning for me.
