    A vessel is quarter filled with a liquid of refractive index \[\mu \]. The remaining parts of the vessel is filled with an immiscible liquid of refractive index \[3\mu \text{/}2\]. The apparent depth of the vessel is 50% of the actual depth. The value of \[\mu \], is

    A)  1                                            

    B)  3/2

    C)  2/3                                       

    D)  4/3

    Correct Answer: B

    Solution :

    \[\Delta h={{h}_{1}}\left( 1-\frac{1}{{{\mu }_{1}}} \right)+{{h}_{2}}\left( 1-\frac{1}{{{\mu }_{2}}} \right)\]
