Question

Classify the bending of light

Answer 1

Explanation:

where index 1 and 2 refer to each medium

In this problem, they tell us that light passes to a medium with a higher index, which is why

n₁ <n₂

let's look for the angle in the second half

sinθ₂ = n₁ /n₂ sin θ₁

θ₂ = sin⁻¹ (n₁ /n₂ sin θ₁)

let's examine the angle argument the quantity n₁ /n₂ <1 therefore the argument decreases, therefore the sine and the angle decreases

Consequently the ray of light should approach normal
