At night, you decide to go for a swim in the apartment complex pool. Your roommate come to find you. The roommate uses a flashlight and shines it on the pool. You are currently underwater and decide to apply what you learned in class that morning about light rays.
You roughly estimate that the roommate shines light rays on to the water at an angle of 52.1°. You know that air has an index of refraction of 1.0. The pool contains an unknown liquid. However, you also estimate that the light ray is refracted at an angle 37.3°. Determine the index of refraction of the unknown liquid.
