Question
The figure shows surface XY separating two transparent media, medium–1 and medium–2. The lines ab and cd represent wavefronts of a light wave travelling in medium–1 and incident on XY. The lines ef and gh represent wavefronts of the light wave in medium–2 after refraction.
Light travels as a
- parallel beam in each medium
- convergent beam in each medium
- divergent beam in each medium
- divergent beam in one medium and convergent beam in the other medium
The correct answer is: parallel beam in each medium
Wavefronts (Normal to rays) are parallel. So rays should also be parallel.
