    Answer:

    T = 0.96 seconds

    Explanation:

    Given that,

    The speed of wave, v = 2.6 m/s

    The distance between wave crests, \lambda=2.5\ m

    We need to find the period of the wave motion. Let T be the period. So,

    v=\dfrac{\lambda}{T}\\\\T=\dfrac{\lambda}{v}\\\\T=\dfrac{2.5}{2.6}\\\\T=0.96\ s

    So, the period of the wave motion is equal to 0.96 seconds.
