Monochromatic light is incident on a glass prism of angle A . If the refractive index of the material of the prism is \mu, a ray, incident at an angle \theta, on the face AB would get transmitted through the face AC of the prism provided :

Correct Answer is : θ>sin−1[µsin(A−sin−1(1µ)]

\theta>\cos ^{-1} [\mu \sin (A+ \sin ^{-1} (\frac{1}{\mu}) ]

\theta< \cos ^{-1} [\mu \sin (A+ \sin ^{-1} (\frac{1}{\mu}) ]

\theta> \sin ^{-1} [\mu \sin (A- \sin ^{-1} (\frac{1}{\mu}) ]

\theta< \sin ^{-1} [\mu \sin (A- \sin ^{-1} (\frac{1}{\mu}) ]
