    The frequency of a light ray is\[6\times {{10}^{14}}Hz\]. Its frequency when it propagates in a medium of refractive index \[1.5\] will be:

    A) \[1.67\times {{10}^{14}}Hz\]

    B) \[9\times {{10}^{4}}Hz\]

    C) \[6\times {{10}^{14}}Hz\]

    D) \[4\times {{10}^{14}}Hz\]

    Correct Answer: C

    Solution :

    The frequency of light does not change when it passes from one medium to, the other medium, hence its frequency will remain \[6\times {{10}^{14}}\,\,Hz\]
