Question
In the fig. name the ray which represents the correct path of light while passing through a glass block.

Solution
A ray entering glass from air bends towards the normal, then bends away from the normal as it emerges. Because the slab faces are parallel, the emergent ray is parallel to the incident ray but laterally displaced.
