Question

what is your observation regarding
angle of refraction when light ray
Passing from denser to rarer medium
(Light incidents on the circular side
the glass slab) ?​

Answer 1

Answer:

The observation is given below.

Explanation:

When the light ray passes from the denser medium to the lighter or the rarer medium, the light ray moves away from the normal. Hence, the angle of refraction will be more.

Answer 2

Answer:

The amount of bending of a light ray as it crosses a boundary between two media is dictated by the difference in the two indices of refraction. When light passes into a denser medium, the ray is bent toward the normal. Conversely, light emerging obliquely from a denser medium is bent away from the normal.
