A uniform, horizontal parallel beam of light is incident upon a prism ...
The ray just above x-axis shall after refraction at curved surface intersect x axis at (A) a distance x1 from O.

The critical angle for air-glass interface is  . the rays above the ray incident on curved surface at i = 370 shall suffer TIR and need not be considered.
The ray incident as curved surface at θ= 370 after refraction intersect curved surface at (B) a distance x2 from O.
