Homework Help: Standing waves!

  1. Oct 20, 2008 #1
    1. The problem statement, all variables and given/known data
    A student wants to establish a standing wave on a wire 1.7 m long clamped at both ends.
    The wave speed is 587 m/s. What is the minimum frequency she should apply to set up standing waves?


    2. Relevant equations
    Not sure...need help here? :)


    3. The attempt at a solution
    I tried 587 / 1.7 which is 345. 294

    Hi physicsya,

    What simple formula has wave speed and frequency in it?

    This is close, in that you have found one of the frequencies of a standing wave. It's just not the minimum frequency.

    For a string that is 1.7m long and clamped at both ends, what is the longest wavelength for a standing wave? (It is not 1.7m.)
