    Four different waves labeled I, II, III, and IV are shown in the given table.
    Which wave has the highest amplitude?

    A)  I                                             

    B)  II

    C)  III                                          

    D)  IV

    Correct Answer: D

    Solution :

      The maximum height of a crest or a trough of a wave is known as its amplitude. It is clear from the given figure that the height of a crest or a trough from the mean position is the maximum in wave IV. Hence, wave IV has the highest amplitude. The correct answer is D.
