Question

the correct position of observing the emergent Ray in the experiment with the glass slab is​

Answer 1

Answer:

a) is the answer

Explanation:

Because the Emergent Ray must be considered from the source.

Answer 2

Explanation:

the angle to the normal decreases with increase in refractive index when a ray incidents the angle decreases but on emergence the refractive index decreases with respect to the denser medium so the angle again increase so the incidence angle and emergent angle become same but due to refraction the position of the line change so the ray is parallel to incident ray . So correct answer is A .
