The index of refraction of benzene is 1.80.The critical angle for total internal reflection, at a benzene-air interface, is about:
A)56°
B)47°
C)34°
D)22°
E)18°

Question

Quizplus · Accepted Answer

The critical angle can be calculated using the formula: sin(θc) = 1/n, where n is the index of refraction. Plugging in the values, we get: sin(θc) = 1/1.80. Solving for θc, we get: θc = 34.15°. Rounding to the nearest degree, the answer is choice C: 34°.
