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 at b and d.

Text Solution

Verified by Experts

The correct Answer is:
B
The gap between consecutive wavefronts in medium 2 is less than that is medium 1. Therefore, wavelength of light in medium 2 is less than that in medium 1 . Therefore, speed of light is more in medium 1 and less in medium 2.
