Solution

The correct option is B Towards the normal due to increase in the speed of light.
When a ray of light enters from glass to water, it bends towards normal due to increase in speed of light.
As we know,

$μ = \frac{c}{v}$
$μ$ for water is less than that of glass, as glass acts as a denser medium. $∴$ the speed of light in glass will be less than that in water.

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

An obliquely incident light ray bends at the surface due to change in speed, when passing from one medium to other. The ray does not bend when it is incident normally. Will the ray have different speed in other medium?

Q. Statement 1: A light ray travelling from a denser medium to a rarer medium bends away from the normal.
Statement 2: The speed of the light do not change as the light gets refracted.
