Choose the correct answer:

"Snell’s law states that the ratio of the sine of the angle of incidence to the sine of the angle of refraction is ______."

The sine of the angle of incidence divided by the sine of the angle of refraction has a constant value. Additionally called Snell's law of refraction. The incident ray was refracted, and at the point of incidence, all normals to the interface of the two mediums are on the same plane.
