Question

When the light travels from rarer to a denser medium

Answer 1

$\mathfrak{\large{\underline{\underline{Answer:-}}}}$

When light travels from the rarer to denser medium.Its speed is decreased due to the change in optical density of the material and light bends towards the normal.

That means, the angle of incidence is greater than angle of refraction.

When light is travel from air to glass here air is rarer medium and glass is denser medium then it bends towards the normal.

Answer 2

● As light travells from a rarer to denser medium the velocity Decreases.
