The angle of a prism is 60^ and its refractive index is 2 . The angle of minimum deviation suffered by a ray of light in passing through it is

Step-by-step solution

aligned & Refractive index, = ( A+ _m 2 ) ( A 2 ) & 2 = ( 60^ + _m 2 ) ( 60^ 2 ) & 2 30^ = ( 60^ + _m 2 ) & 45^ = ( 60^ + _m 2 ) & _m=30^ aligned
