        A parallel beam of monochromatic unpolarised light is incident on a transparent dielectric plate of refractive indie\[\frac{1}{\sqrt{3}}\]. The reflected beam is completely polarised. Then the angle of incidence is

    A)  \[30{}^\circ \]                                  

    B)  \[60{}^\circ \]

    C)  \[45{}^\circ \]                                  

    D)  \[75{}^\circ \]

    Correct Answer: A

    Solution :

                    Angle of incidence,\[{{i}_{p}}={{\tan }^{-1}}(\mu )\]\[={{\tan }^{-1}}\left( \frac{1}{\sqrt{3}} \right)=30{}^\circ \]
