Snell's laws proof using Huygen's principle | Wave optics | Physics | Khan Academy
Huygen's principle states that every point on a wavefront behaves as a source for secondary waves, whose common tangent (envelop) becomes the new wavefront. Using this principle, let's prove Snell's law of refraction - Ratio of the sine of angle of incidence to the sine of the angle of refraction is a constant.
