    The frequency of a tuning fork is 256 Hz. The velocity of sound in air \[344\text{ }m{{s}^{-1}}.\] The distance travelled (in metres) by the sound during the time in which the tuning fork completes 32 vibrations is:

    A)  21                                         

    B)  43

    C)  86                                         

    D)  129

    Correct Answer: B

    Solution :

                     Wavelength of sound, \[\lambda =\frac{v}{n}=\frac{344}{256}m\] So, distance travelled by the sound in 32 vibrations is \[s=32\lambda \] \[=32\times \frac{344}{256}=43\,m\]
