Light travels as a [2007]

Question

The figure shows a 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. [2007]

Q. Light travels as a

Smart Achievers · Accepted Answer

(1)

For plane wavefronts, the beam of light is parallel. Hence, light travels as a parallel beam in each medium.

Solution

1 parallel beam in each medium

2 convergent beam in each medium

3 divergent beam in each medium

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

Ans.
(1)

For plane wavefronts, the beam of light is parallel. Hence, light travels as a parallel beam in each medium.
