    Two waves having sinusoidal waveforms have different wavelengths and different amplitude. They will be having                    [BHU 2005]

    A)            Same pitch and different intensity                                 

    B)            Same quality and different intensity

    C)            Different quality and different intensity                      

    D)            Same quality and different pitch

    Correct Answer: A

    Solution :

               The pitch depends upon the frequency of the source. As the two waves have different amplitude therefore they having different intensity. While quality depends on number of harmonics/overtone produced and their relative intensity. Assuming that their frequencies are the same.
