  • question_answer
    The refractive indices of water, glass and diamond are 1.33,1.50 and 2.40 respectively. The refractive index of diamond relative to water and of glass relative to diamond respectively are nearly

    A)  1.80,0.625          

    B)         0554,0.625

    C)  1.80, 1.6          

    D)         0.554,1.6

    Correct Answer: A

    Solution :

     Given:\[{{\mu }_{w}}=1\times 33,\,\,{{\mu }_{g}}=1.5\]and\[{{\mu }_{0}}=2\times 40\] Now,     \[_{w}{{\mu }_{D}}=\frac{{{\mu }_{D}}}{{{\mu }_{w}}}=\frac{2\cdot 40}{1\cdot 33}=1.80\] Further \[_{D}{{\mu }_{g}}=\frac{{{\mu }_{g}}}{{{\mu }_{D}}}=\frac{1\cdot 50}{2\cdot 40}\mathbf{=0}\mathbf{.265}\]
