The angle of minimum deviation for a prism of angle A is 180-2 A . The refractive index is

Options

  1. AA 2
  2. BA 2
  3. CA 2
  4. DA 2

Correct answer

D. A 2

Step-by-step solution

Refractive index is given by n= ( A+ _m 2 ) A 2 Given, _m=180^ -2 ~A aligned & n= ( A+180^ -2 A 2 ) A 2 & n= ( 180^ 2 - A 2 ) A 2 & n= A 2 A 2 = A 2 . aligned
