Question

If a ray of light is incident at 35 degree on the surface of a glass slab, then what will be the angle of emergence?​

Answer 1

Explanation:

The answer would be 30°.

Consider the line in green as the Ray.

Now, draw a normal to the interface of the glass slab.

By the question, we got that 60° is the angle between the surface of the slab and the Ray.

The angle of incidence is angle between the Ray and the normal.

You get 90°–60°=30°.

Answer 2

Answer:

90°–60°=30°.
