Question

a light ray entering glass from water – Dash​

Answer 1

when a light ray entering glass from water is example of refraction

Answer 2

Answer:

A light ray coming from water to glass will bend towards the normal.

Explanation:

This is because the optical density of water is lesser than the optical density of glass. Or, we can say that the refractive index of glass is more than that of water.

• When light rays enter from an optically rarer medium to an optically denser medium, it bends towards the normal because of reduction in speed.
• When it enters from an optically denser medium to an optically rarer medium, it moves away from the normal because of increase in its speed.
