Fig. shows a surface XY separating two transparent media, medium 1 and medium 2. Lines ab and cd represent wavefronts of a light wave travelling in medium 1 and incident on XY. Line ef and gh represent wavefront of the light wave in medium 2 after rafraciton.
Speed of light is

A

the same in medium-`1` and medium-`2`

B

larger in medium-`1` than in medium-`2`

C

larger in medium-`2` than in medium-`1`

D

different ab `b` and `d`

Text Solution

Verified by Experts

The correct Answer is:
B
Ray is bending towards normal.
So, medium `1` should be rarer and medium `2` should be denser.
So, `V_(1)gtV_(1)`.
