    Complete question is;

    A fisherman’s boat moves up and down periodically due to water waves. The boat travels from its highest to its lowest point, a vertical distance of 0.60 m, in 2.0 s. The horizontal distance between wave crests is 7.0 m. (a) What is the period of the wave motion? (b) What is the frequency of the wave motion? (c) What is the amplitude of each wave

    Answer:

    A) Period = 4 s

    B) Frequency = 0.25 Hz

    C) Amplitude = 0.3 m

    Explanation:

    A) We are told that the distance it takes for the boat to travel from its highest to its lowest point is 2 s.

    Thus, t = 2 s

    Now, in waves, period (T) it the time between two successive waves.

    This means that;

    T = 2t

    T = 2 × 2

    T = 4 s

    B) Also, the frequency(f) is given by the formula;

    f = 1/T

    f = 1/4

    f = 0.25 Hz

    C) We are given a vertical distance of 0.60 m from highest to lowest point of waves.

    Now, amplitude is half of this distance.

    Thus;

    Amplitude(A) = 0.6/2

    A = 0.3 m
