WebHuygen'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. Created by Mahesh Shenoy. Sort by: WebThe basic principle underlying the method is that a wavefront can be evolved by repeated application of local ray tracing from a set of points lying on the wavefront surface. Thus, for some given time step δt, a new wavefront is deﬁned by the end points of the rays traced from the old wavefront, as illustrated schematically in Fig. 28.
