When light ray penetrates into the denser medium from the abnormal bend to the normal In this case the magnitude of the curvature of the parallel radiation is the same. Thus, the emergent ray is parallel to the incident ray.
Why does a light ray incident on a rectangular glass slab immersed in any medium emerges parallel to itself? Explain using a diagram.
