When a light ray in air enters glass with index of refraction 1.60,what is the greatest angle of refraction that can occur?
A) 90.0$^{\circ}$
B) 56.2$^{\circ}$
C) 52.2$^{\circ}$
D) 38.7$^{\circ}$
E) 0.0$^{\circ}$

Quizplus · Accepted Answer

The greatest angle of refraction occurs when the angle of incidence is 90 degrees. Using Snell's Law, n1*sin(theta1) = n2*sin(theta2), where n1 = 1 (air) and n2 = 1.60 (glass), the angle of refraction (theta2) is approximately 38.7 degrees.
