An incident ray of light strikes a diamond at an angle of 45 degrees The index of refraction of air is 1 point 0 0 0 3 and the index of refraction of a diamond is 2 point 4 2 What is the angle of refraction rounded to the nearest whole number?
Use Snell’s law: n₁ sin(θ₁) = n₂ sin(θ₂). Thus sin(θ₂) = (1.0003/2.42) sin(45°) ≈ 0.292, so θ₂ ≈ 17°. The correct choice is 17 degrees.
