Solve the problem.

When light travels from one medium to another—from air to water, for instance—it changes direction. (This is why a pencil, partially submerged in water, looks as though it is bent.) The angle of incidence θ_i is the angle in the first medium; the angle of refraction θ_r is the second medium. (See illustration.) Each medium has an index of refraction—n_i and n_r, respectively—which can be found in tables. Snell's law relates these quantities in the formula
n_i sinθ_i = n_r sin θ_r
Solving for θ_r, we obtain
θ_r = sin^-1

Find θ_r for fused quartz (n_i = 1.46), ethyl alcohol (n_r = 1.36), and θ_i = 8.5°.
