An incident ray in air (n=1.0) is approaching the boundary with glass (n=1.52) at an angle of incidence of 31.7 degrees. Calculate the angle of refraction.

Use Snell's law: sin(i)/sin(r) = nglass/nair where i is angle of incidence and r is angle of refraction.
.sin(31.7°)/sin(r) = 1.52
sin(r) = sin(31.7°)/1.52
r = sin-1(sin(31.7°)/1.52)
r ≈ 20.2°
