Diamond has an index of refraction of 2.419.What is the critical angle for internal reflection inside a diamond that is in air?
A)24.4 $\degree$
B)48.8 $\degree$
C)155 $\degree$
D)131 $\degree$

Question

Quizplus · Accepted Answer

The critical angle can be calculated using the formula: critical angle = arcsin(1/n), where n is the index of refraction. For diamond, arcsin(1/2.419) ≈ 24.4°.
