10. A layer of oil (n = 1.45) floats on an unknown liquid. A ray of light originates in the oil and passes into the unknown liquid. The angle of incidence is 64.0°, and the angle of refraction is 53.0°. What is the index of refraction of the unknown liquid?

 

Snell’s Law gives us

 

Solve for the unknown index of refraction
