Homework Help: Sinusoidal Oscillator Quick Question

  1. Feb 8, 2007 #1
    1. The problem statement, all variables and given/known data
    Drive one end of the string with sinusoidal oscillator of frequency 100hz. What velocity is required to setup a standing wave with 5 segments?

    2. Relevant equations
    I know for standing wave that fn = nV/2L and you can isolate out velocity variable.

    3. The attempt at a solution

    Though I'm not very familiar if the string is not tied down at both ends and I was wondering if someone could explain how to obtain the velocity from the 2 givens.

    You don't have enough information. You also need the total length of the string.

    The standing wave in a string fixed at one end and free at the other end will look the same as in a pipe closed at one end and open at the other end.
