Light is refracted through a diamond. If the angle of incidence is 30°, and the angle of refraction is 12°, what is the index of refraction?
A) 1.3
B) 2.4
C) 2.6
D) 1.8
E) 0.4

Quizplus · Accepted Answer

The index of refraction can be calculated using Snell's law: n=sin(i)/sin(r), where i is the angle of incidence and r is the angle of refraction. Plugging in the given values, we get n=sin(30°)/sin(12°) ≈ 2.4. Therefore, the best choice is B) 2.4.
