Answer:
The angle of refraction is option b: 17°.
Explanation:
We can find the angle of refraction by using Snell's law:
Where:
n₁: is the index of refraction of the medium 1 (air) = 1.0003
n₂: is the index of refraction of the medium 2 (diamond) = 2.42
θ₁: is the angle of incidence = 45°
θ₂: is the angle of refraction =?
Hence, the angle of refraction is:
Therefore, the correct option is b: 17°.
