Books Books When a ray of light passes from one medium to another, it is refracted so that the ratio of the sine of the angle of incidence to the sine of the angle of refraction is equal to the ratio of the velocities in the two media.

...refraction for air is very close to 1 so the ratio ca/cw is very close to 1.33. Law of Refraction. The ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant. In our derivation, there was no dependence on direction, so our result would... ## A-level Physics
