Sound Waves

    1. The problem statement, all variables and given/known data

    To check the frequency of an unknown tuning fork, it is struck with one that vibrates at 256 Hz. While they vibrate together, beats with a period of 2 seconds are heard. What are the two possible frequencies for the unknown fork?

    2. Relevant equations

    f1-f2 = beats

    1/T = f

    3. The attempt at a solution
    f1= 256Hz
    Tb = 2 s
    f = 1/2s = .5 Hz
    f1-f2 = .5 Hz
    f2 = 256.5 or 255.5

    Is this correct? I think the wording threw me off.
