    Answer:

    0.28 m/s

    Explanation:

    From the equation of a moving wave,

    V = λf……………… Equation 1

    Where V = speed of the water wave, λ = wave length of the water wave, f = frequency of the water wave.

    Given: λ = 7.0 cm = 0.07 m, f = 4 Hz.

    Substitute into equation 1

    V = 0.07(4)

    V = 0.28 m/s.

    Hence the speed of the water wave = 0.28 m/s
