WebJun 23, 2024 · The concept of a wavefront plays a central role in that branch of acoustical theory known as geometrical acoustics or ray acoustics.A wavefront is any moving surface along which a waveform feature is being simultaneously received (see Fig. 8.1).For example, if the time history of acoustic pressure has a single pronounced peak that arrives at x at … 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:
