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

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

    B)  \[\sqrt{3}\]   

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

    D)  \[\frac{1}{\sqrt{3}}\]

    Correct Answer: B

    Solution :

    Since, reflected and refracted waves are perpendicular to each other. \[\therefore \] So, refractive index \[\mu =\tan {{i}_{0}}=\tan {{60}^{o}}\]                                                 \[=\sqrt{3}\]
