Solve question 36

Q. For two structures namely S1 with n1 45 4  and n2 3 2 ,   and   S 2   with   n 1   = 8 5 and   n 2   = 7 5  and taking the refractive index of water to be 4/3 and that of air to be 1, the correct option (s) is (are) 

    (A) NA of S1 immersed in water is the same as that of S2 immersed in a liquid of refractive index  16 3 15

     (B) NA of S1 immersed in liquid of refractive index  6 15  is the same as that of S2 immersed in water 

     (C) NA of S1 placed in air is the same as that of S2 immersed in liquid of refractive index  4 15
   
      (D) NA of S1 placed in air is the same as that of S2 placed in water
