Homework Help: Vibrational Frequence

  1. Feb 4, 2007 #1
    1. The problem statement, all variables and given/known data
    A guitar string produces 4 beat/s when sounded with a 350-Hz tuning fork and 9 beat/s when sounded with a 355-Hz fork. What is the vibrational frequency of the string? Explain your reasoning.

    2. Relevant equations

    3. The attempt at a solution
    I'm not quite sure how to start solving this problem. I know that frequency is velocity divided by wavelength. What equation or equations that have beat/s as variables could I use to solve this problem?
