Question

What happens to a ray of light when it travels obliquely from an optically denser to an optically rarer medium?

• A. It bends away from the normal
• B. It bends towards the normal.
• C. It can bend towards or away from the normal.
• D. It does not bend.

Answer 1

The correct option is A It bends away from the normal

When a ray of light travels from an optically denser to an optically rarer medium, it bends away from the normal. This happens because the ray of light speeds up in the rarer medium.
