Question

Angle of prism=60 and angle of minimum deviation = 30 . Find refractive index of prism?

Answer 1

refractive index is =Sin( A+Dm)/2
                              ---------------------
                              sin(A/2)
        =sin(60+30)/2
          ----------------
          sin30
  sin45/sin 30
=1/√2/1/2    = √2=1.414
