Question

b) How does the refracted ray behave when it passes from:
(i) a rarer medium to a denser medium
(ii) a denser medium to a rarer medium​

Answer 1

Answer:

1 and 2

Explanation:

when a ray of light goes from rarer medium to denser medium it bends towards the normal.

when a ray of light goes from denser medium to rarer medium it bends away from the normal.

Answer 2

Explanation:

(1)When light rays travel from optically rarer medium to denser medium then they bend towards normal. ... When light rays travel from air into glass or from air into water, it bends towards normal. This is because the speed of light rays decrease while travelling from air into glass or water.

(2)When light travels from a denser medium to a rarer medium, it bends away from the normal, as illustrated to the left. This behavior follows from Snell's Law
