Question

16. A ray of light is travelling from a rarer medium to a denser medium. While entering the
denser medium at the point of incidence, it
(a) goes straight into the second medium
(b) bends towards the normal
(c) bends away from the normal
(d) does not enter at all

Answer 1

Answer:

Due to refraction of light, when a ray of light passes from a rarer medium to a denser medium, bends towards the normal to the boundary between the two media. ... Hence, when a ray of light from air enters a denser medium, it bends towards the normal.

Answer 2

Explanation:

bends towards the normal
