    Unpolarised light is incident on a dielectric of refractive index\[\sqrt{3}\]. What is the angle of incidence if the reflected beam is completely polarised?

    A) \[30{}^\circ \]              

    B) \[45{}^\circ \]  

    C) \[~60{}^\circ \]           

    D) \[75{}^\circ \]

    Correct Answer: C

    Solution :

    [c] \[\mu =\tan i\] \[\Rightarrow \,i={{\tan }^{-1}}(\mu )={{\tan }^{-1}}(\sqrt{3})={{60}^{o}}\]
