Assertion: A total reflecting prism is used to erect the inverted image without deviation. Reason: Rays of light incident parallel to base of prism emerge out as parallel rays.

The beam now strikes the face B C of the prism at an angle of incidence less than the critical angle hence it suffers refraction from glass to air and bends away from the normal. The beam emerges out parallel to the base. As a result of refraction, on emergence the rays are inverted.
