Answer:

Introduction:
The given 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 traveling in medium-1 and incident on XY. The lines ef and gh represent wavefronts of the light wave in medium-2 after refraction. We need to determine how light travels in each medium.

Explanation:
To understand how light travels in each medium, we need to consider the properties of light and the laws of refraction.

Properties of Light:
1. Light travels in straight lines.
2. Light can be reflected, refracted, and absorbed.
3. Light travels at different speeds in different media.

Laws of Refraction:
1. The incident ray, the refracted ray, and the normal to the surface at the point of incidence all lie in the same plane.
2. The ratio of the sine of the angle of incidence to the sine of the angle of refraction is constant, known as the refractive index.

Analysis:
In the given figure, the lines ab and cd represent wavefronts of a light wave traveling in medium-1. As light travels in straight lines, the wavefronts are parallel to each other. When the light wave reaches the surface XY, it undergoes refraction.

The lines ef and gh represent wavefronts of the light wave in medium-2 after refraction. Since the wavefronts are still parallel to each other, it implies that the light wave is traveling as a parallel beam in medium-2.

Conclusion:
Based on the analysis, we can conclude that the light travels as a parallel beam in each medium, as represented by the lines ab and cd in medium-1 and the lines ef and gh in medium-2. Therefore, the correct answer is option 'A' - Light travels as a parallel beam in each medium.
