Question

Why the light ray bends towards normal from rarer medium to dender medium during refraction

Answer 1

This is called Snell’s law. Light bends at the interface between two mediums, depending on their index of refraction.

Answer 2

Answer:

Explanation:

When light ray travels from rarer to denser, the speed of light get decreased from 3×10 to 2.25×10 so it bend towards normal
