Question

QUES
1.
A ray of light travelling in air enters obliquely into water. Does the light
ray bend towards the normal or away from the normal? Why?
​

Answer 1

Answer:

bends

towards the normal because the speed of light decreases when it travels from air to water.

Answer 2

$\large\red{\bf{\underline{\underline {Answer :-}}}}$

The light ray bends towards the normal. When a light ray enters from an optically rarer medium (which has low refractive index) to an optically denser medium (which has a high refractive index), its speed slows down and bends towards the normal. As water is optically denser than air, a ray of light entering from air into water will bend towards the normal.
