As light travels from one medium to another (for example, from air to glass), it refracts, or "bends." If v₁ is the speed of light through one medium, and 2 is the speed of light through another medium, then according to Snell's Law, sin(01) V1 sin(82) V2 == where ₁ is the angle of incidence, and 2 is the angle of refraction. Incident Ray Normal Line Angle of incidence 0₁ Air Surface Angle of refraction 0₂ Refracted Ray V1 The fraction is called the index of refraction. For a beam of light passing from air to water, the index of refraction is V2 1.33. If a ray of light passes through the surface of a water at an angle of incidence of 54°, what is the angle of refraction?
