Questions)-
A rectangular glass slab having refractive index 3
is silvered at one surface as shown in figure. Light
ray will deviate by angle when it cross the
glass slab.
30°
Silvered​

Answer 1

Answer:

Explanation:

Given that

θ=30°

if wall does not present then the light will follow a-b-c path but due to wall it deviate from original path and known as deviation of ray.

lets take deviation angle is δ.

We know that

θ + δ = 180°

θ=30°

δ =  180° - 30°

δ =120°
