Question

When a light ray passes from a rarer medium to a denser medium

a) r < i b) r > i c) r = i d) all of these​

Answer 1

Answer:

answer is b

Explanation:

because when a light ray passes from rarer medium to denser medium the ray bends towards the normal so b is correct answer

Answer 2

Answer:

Option B)r > i is correct.

Explanation:

Refraction id the bending of light rays after entering a medium where its speed is different.

Due to refraction of light passes from rarer medium to a denser medium bends towards between the two media. The amount of bending depends on the indices of refraction of the two media. Hence,when a ray of light from air enters a denser medium, it bends towards the normal.
