    A source of sound producing wavelength of 50 cm is moving away from stationary observer with \[\frac{1}{5}\]th speed of sound. Then, what is the wavelength of sound heard by observer?

    A)                  70 cm                                  

    B)                  55 cm

    C)                  40 cm                                  

    D)                  60 cm

    Correct Answer: D

    Solution :

                     Wavelength \[\lambda =\lambda \left( \frac{v+{{v}_{S}}}{v} \right)\]                 \[\lambda =50\left( \frac{330+\frac{300}{5}}{330} \right)\]                 \[\lambda =50\left( \frac{330+66}{330} \right)\]                 \[=50\left( \frac{396}{330} \right)=50\times \frac{6}{5}=60\,cm\]
