JEE Main & Advanced Physics Ray Optics Question Bank Refraction of Light at Plane Surfaces

  • question_answer
    A ray of light is incident on a transparent glass slab of refractive index 1.62.  The reflected and the refracted rays are mutually perpendicular. The angle of incidence is [MP PET 2002]

    A)            58.3o                                        

    B)            50o

    C)            35o

    D)            30o

    Correct Answer: A

    Solution :

               \[\mu =\tan i\] Þ i = \[{{\tan }^{-1}}\mu ={{\tan }^{-1}}1.62=58.3{}^\circ \]
