Answer 1

Answer:

2 option

Explanation:

When a light ray enters the rectangular glass slab, which is a denser medium than air, it bends towards the normal. When it emerges back to the rarer medium(air), it bends away from the normal and becomes parallel to the incident ray. So, the angle of incident is always greater than the angle of refraction and always equal to the angle of emergence. i.e. ∠i>∠r, ∠i=∠e∠i>

According to this, the correct relation between the given angles is, θ1>θ2 but θ1=θ3

Hence, the correct answer is option 2.
