JEE Main & Advanced Physics Wave Optics / तरंग प्रकाशिकी Question Bank Polarisation of Light

  • question_answer
    Polarising angle for water is 53°4'. If light is incident at this angle on the surface of water and reflected, the angle of refraction is                                                                   [TNPCEE 2002]

    A)            53°4'                                        

    B)            126°56'

    C)            36°56'                                      

    D)            30°4'

    Correct Answer: C

    Solution :

               \[{{\theta }_{P}}+r=90{}^\circ \] or r = 90o ? qP = 90° ? 53°4' = 36°56'.
