In figure, ABC is the cross section of a right-angled prism and ACDE is the cross section of a gless slab. The value of theta so that light incident normally on the face AB does not cross the face AC is (given sin^(-1)(3//5)=37^(@)).

A ray of light is incident normally on one face of a prism of refracting angle A. After travelling through prism, the ray emerges from the second refracting surface making an angle of deviation of delta . The refractive index of the material of prism is
