    Let p denote the time of one period. Then

    f = \frac1p . Plug in the value of p and you'll get

    f = 14.62 \ \frac1s

    I take the value of the sound speed in water from my previous post. From

    f \cdot l  = 1485\ \frac ms~\implies~ 14.62 \ \frac1s \cdot l  = 1485\ \frac ms you can calculate l.

    (For confirmation only: 101.6 m)
