    Each of the properties of sound in List-\[\text{I}\] primarily depends on one of the quantities in List-\[\text{II}\text{.}\] Select the correct answer (matching List-\[\text{I}\] with List-\[\text{II}\text{.}\]) as per code given below the lists
    \[\text{List}\,\text{-I}\] \[\text{List}\,\text{-II}\]
    (A) Loudness (1) Waveform
    (B) Pitch (2) Frequency
    (C) Quality (3) Intensity
    Codes:

    A) A-1     B-2           C-3

    B) A-3      B-2           C-1

    C) A-2      B-3          C-1

    D) A-2      B-1           C-3

    Correct Answer: B

    Solution :

    The loudness that we sense is related to the intensity of the sound though it is not directly proportional. A sound of high pitch is said to be shrill and its frequency is high. A sound of low pitch is said to be grave and its frequency is low. The quality of sound is given by waveform.
