Question

4. If index of refraction 1 is 1.5, index of refraction 2 is 2.0, and the angle of incidence is 45 degrees, what is the angle of refraction?
15 index ofreaction 21820 and the angle of medence is as degres what's the angle of reaction

16 degrees

32 degrees

48 degrees

64 degrees

Answer 1

Answer: The angle of refraction is 32°

Explanation:

By snell law, we have that:

n₁*sen(θ₁) = n₂*sen(θ₂)

Where n₁ = 1.5

n₂ = 2.0

θ₁ = 45°.

then we want to find the angle of refraction.

1.5*sin(45°) = 2*sin(x)

x = Asin(1.5*sin(45°)/2) = 32°
