Find the length of string and speed of wave in string

  1. Mar 23, 2008 #1
    1. The problem statement, all variables and given/known data
    Find the length of string and speed of wave in string if frequency of given wave is 850 hz and the wavelength is 0.173m? The string is in a tube that is closed at both ends.




    2. Relevant equations
    v=(T/(m/L)^.5

    3. The attempt at a solution

    I found the speed using v=frequency*wavelength.
    How do i find the length of the string?
    i dont know the mass or the tension

    This is a standing wave. Have you read about that?

    Assume that the frequency given is that of the fundamental. What is the relationship between the wavelength and the length? In this case, the ends of the string are both nodes.
