Answer:
A ray passing through the normal emerges through normal .
Answer:
When a ray passes from a less dense medium (such as air) to a denser one (such as glass), the ray is bent, or refracted, in such a way that it emerges from the interface in a directin which lies closer to the perpendicular, which calls "normal", to that interface.
