Question

with the the help of a ray diagram show the refraction of light from an optically rarer medium to a denser medium​

Answer 1

Answer:

When light passes from a less dense to a more dense substance, (for example passing from air into water), the light is refracted (or bent) towards the normal. The normal is a line perpendicular (forming a 90 degree angle) to the boundary between the two substances.
