    Answer:

    0.33 Hz

    Explanation:

    The frequency (f) is the rate of occurrence while the Period (T) is the time of occurrence. These two quantities are reciprocal to one another. The frequency refers to the number of cycles per second.

    Hence, the equation is:

    f = 1/T or T=1/f

    The period in this question is 3seconds i.e. 1 cycle every 3 seconds, hence, the frequency will be:

    f = 1/3

    = 0.33333333

    Approximately to 2 d.p = 0.33Hz

    Therefore, the frequency of the water waves striking the dock is 0.33Hz
