    A ray of light strikes a material's slab at an angle of incidence \[{{60}^{o}}\]. If the reflected and refracted rays are perpendicular to each other, the refractive index of the materials is :

    A)  \[\frac{1}{\sqrt{3}}\]                            

    B)  \[\frac{1}{\sqrt{2}}\]

    C)  \[\sqrt{2}\]                               

    D)  \[\sqrt{3}\]  

    Correct Answer: D

    Solution :

    From the Brewster's Law\[\mu \,=\tan {{i}_{P}}=\tan \,{{60}^{0}}=\sqrt{3}\]
