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 θi is the angle in the first medium; the angle of refraction θr is the second medium. (See illustration.) Each medium has an index of refraction—ni and nr, respectively—which can be found in tables. Snell's law relates these quantities in the formula
ni sinθi = nr sin θr
Solving for θr, we obtain
θr = sin-1
Find θr for fused quartz (ni = 1.46), ethyl alcohol (nr = 1.36), and θi = 8.5°.
