The critical angle for total internal reflection at a liquid-air interface is 45.0^\circ.
1. If a ray of light traveling in the liquid has an angle of incidence of 32.5^\circ at the interface with respect to the normal, what angle does the refracted ray in the air make with the normal?
2. If a ray of light traveling in air has an angle of incidence of 32.5^\circ at the interface with respect to the normal, what angle does the refracted ray in the liquid make with the normal?
