    The speed of a wave in a certain medium is 960 m/s. If 3600 waves pass over a certain point of the medium in 1 minute, the wavelength is                                                     [MP PMT 2000]

    A)            2 metres                                 

    B)            4 metres

    C)            8 metres                                 

    D)            16 metres

    Correct Answer: D

    Solution :

               \[\,n=\frac{3600}{60}=60\]Hz  Þ \[\lambda =\frac{v}{n}=\frac{960}{60}=16\,m\]
