    The frequency of a tuning fork is 384/s and velocity of sound in air is 352 m/s. Find how far the sound has traversed while fork completes 36 vibrations.

    A)  33 m          

    B)  16.5 m

    C)  11 m          

    D)  22 m

    Correct Answer: A

    Solution :

    The distance moved by the wave in the time of one complete oscillation of a particle of the medium is called the wavelength (X). Also \[\lambda =\frac{velocity\text{ }\left( v \right)}{frequency\text{ }\left( n \right)}\] Given, \[n=384/s,\,v=352\,m/s\] Distance moved in 36 vibrations is \[\lambda =\frac{36\times 352}{384}=33\,m\].
