Homework Help: Frequency of second harmonic

  1. Jul 22, 2009 #1
    1. The problem statement, all variables and given/known data

    If the fundamental frequency for a rope fixed at both ends is 30Hz, what is the frequency of the second harmonic?

    2. Relevant equations


    3. The attempt at a solution

    correct answer is 60Hz. Can somebody please explain? Thank you.

    In the fundamental mode of vibration, the rope contains one loop which is λ/2. In the second harmonic the number of loops are two. Then what is the new wavelength?
