Answer 1

When a ray of light travelling in an optically denser medium, emerges into an optically less denser medium, it deviates away from normal.

Explanation:

When light travels obliquely from an optically denser medium to a rarer medium, it bends away from the normal. It does not necessarily get reflected.
