Question

The light ray emerging out from the glass slab is laterally displaced with respect to the incident light ray. State the reasons for this observation. 2 points

Answer 1

Answer:

Explanation:

The ray of light is incident on the glass slab the ray get refracted twice and comes out from the other surface as the emergent ray.The emergent ray shows a lateral shift from the original path of the light. When the light is passing through the glass its velocity decreases and when comes out of the glass slab its velocity increases and the light ray traces the same direction in the air.

Hence incident and emergent rays are parallel to each other.

Answer 2
