Carbon disulfide (n = 1.63) is poured into a container made of crown glass (n = 1.52). What is the critical angle for internal reflection of a ray in the liquid when it is incident on the liquid-to-glass surface?

Expert Answer:

Refractive index of glass with respect to liquid:
n = 1.52/1.63 = 0.9325
thus critical angle, i = sin-1(n) = 68.8
