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

  • question_answer
    Two Nicols are oriented with their principal planes making an angle of 60°. The percentage of incident unpolarized light which passes through the system is 

    A)            50%                                          

    B)            100%

    C)            12.5%                                      

    D)            37.5%

    Correct Answer: C

    Solution :

                       Intensity of polarised light from first polarizer \[=\frac{100}{2}=50\] \[I=50{{\cos }^{2}}60{}^\circ =\frac{50}{4}=12.5\]
