A beam of light passes from air to ethanol, with index of refraction of 1.36. If the angle of incidence (1) is 30.0 degrees, then calculate he angle of refraction, after light passes through ethanol and enters into air.

I got 30.0 because wouldn't the light beam upon re-entering air be parallel to the original?
