  1. Solved it. Thanks anyway.

  3. Wait, how do you know the velocity of the wave? Doesn't that only work for a wave in air? Shouldn't you use a different value for the velocity on a string?

    EDIT: It really doesn't matter, though. Everything but the length and frequency will cancel.

    So if F = 440hz, then F1 = 440hz = xF2 = x(523hz), right? Where x is some constant to get 440 (don't want to calculate it =/ )

    So then F1 = m(v/(2*30)) = xm(v/(2*L))

    You know everything but L by now and everything else cancels.
