    During a tsunami, oceanographers observed that the maximum height of an ocean wave from the ocean surface was 15 m. The created ocean wave can be represented as

    A)

    B)

    C)  

    D)  

    Correct Answer: B

    Solution :

      The maximum height of a crest or a trough is known as the amplitude of a wave. Since the observed ocean wave rose to a maximum height of 15 m, the amplitude of the created wave was 15 m. Only the figure in alternative B shows the maximum height of the wave from the mean position as 15 m. The correct answer is B.
