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.

Light travel as a

A

parallel beam in each medium

B

convergent beam in each medium

C

divergent beam in each medium

D

divergent beam in one medium and convergent beam in the other medium

Text Solution

Verified by Experts

The correct Answer is:
a
Wavefronts are parallel in both media. Therefore, light which is perpendicular to the wavefront travels as a parallel beam in each medium.
