Monochromatic light is incident on a glass prism of angle A. If the refractive index of the material of the prism is $\displaystyle \mu$, a ray, incident at an angle $\displaystyle \theta$, on the face AB would get transmitted through the face AC of the prism provided :
Official answer
(1)
$\displaystyle \theta>\sin ^{-1}\left[\mu \sin \left(A-\sin ^{-1}\left(\frac{1}{\mu}\right)\right)\right]$
