    On a glass plate a light wave is incident at an angle of \[60{}^\circ \]. If the reflected and refracted waves are mutually perpendicular, the  refractive index of material is :

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

    B) \[\frac{3}{2}\]

    C) \[\sqrt{3}\]                                        

    D) \[\frac{\sqrt{3}}{2}\]

    Correct Answer: C

    Solution :

    By Brewsters law, \[\mu =\tan {{i}_{p}}\] \[\mu =\tan \,{{60}^{o}}=\sqrt{3}\]
