Paragraph:
The figure shows a surface separating two transparent media, medium-1 and medium-2. The lines and represent wavefronts of a light wave travelling in medium-1 and incident on . The lines ef and represent wavefronts of the light wave in medium-2 after refraction.
Question: Light travels as a
Question: Light travels as a
Options
- Aparallel beam in each medium
- Bconvergent beam in each medium
- Cdivergent beam in each medium
- Ddivergent beam in one medium and convergent beam in the other medium
Correct answer
A. parallel beam in each medium
Step-by-step solution
Wavefronts are parallel in both media. Therefore, light which is perpendicular to wavefront travels as a parallel beam in each medium. Hence, the correct option is (a).
