    The frequency of a light ray is \[3.2\times {{10}^{3}}N\]Hz. Its frequency when it  propagates in a medium of refractive index 1.5, will be :

    A) \[4.2\times {{10}^{3}}N\]                            

    B) \[5.2\times {{10}^{3}}N\]

    C) \[{{10}^{2}}\]                    

    D) \[{{10}^{-2}}\]

    Correct Answer: C

    Solution :

    The frequency of light rays remains unchanged when it passes through one medium to another medium. Therefore the frequency of ray will be \[{{\tan }^{-1}}\left( \frac{1}{5} \right)\] Hz.
