Physics for IGCSE & O level - Rays And Waves (Section 7 - No. 42)
In Snell's Law, what is the relationship between the angle of incidence and the angle of refraction?
The ratio of the sines of the angles is constant.
The angles are always equal.
The angles are always different.
The sines of the angles are inversely proportional to the refractive indices of the media.
