    The frequency of a rod is 200 Hz. If the velocity of sound in air is \[340\,m{{s}^{-1}}\], the wavelength of the sound produced is [EAMCET (Med.) 1995;  Pb. PMT 1999; CPMT 2000]

    A)            1.7 cm                                     

    B)            6.8 cm

    C)            1.7 m                                       

    D)            6.8 m

    Correct Answer: C

    Solution :

               \[\lambda =\frac{v}{n}=\frac{340}{200}=1.7\]\[m\]
