Question

What happens when a ray of light passes from
(i) An optically rarer to an optically denser medium?​

Answer 1

Answer:

As the light goes from an optically denser to an optically rarer medium, it bends away from the normal. Hence, the angle of refraction is greater than the angle of incidence. ... Thus, the angle of refraction has to be greater than the angle of incidence i.e. it bends away from the normal.

Answer 2

Answer:

hope this helps plz mark my answer brainlist plz plz

Explanation:

As the light goes from an optically denser to an optically rarer medium, it bends away from the normal. Hence, the angle of refraction is greater than the angle of incidence.

For optically denser medium, the refractive index n1 is greater than that of the rarer medium n2. Thus, the angle of refraction has to be greater than the angle of incidence i.e. it bends away from the normal.
