    Question

    Which of the following is the time taken for one

    complete oscillation of a sound wave in the density of the medium?
    A Amplitude Correct Answer Incorrect Answer
    B Wavelength Correct Answer Incorrect Answer
    C Frequency Correct Answer Incorrect Answer
    D Time period Correct Answer Incorrect Answer

    Solution

    Time period: • The pendulum also completes one oscillation when its bob moves from one extreme position to the other extreme position and comes back to the initial position and is known as oscillation and the time taken by the pendulum to complete one oscillation is called its time period. • As the wavelength is inversely proportional to the frequency, the wavelength will decrease when the frequency increases which results in higher tones.
