WebApr 12, 2024 · Huygens' Principle Statement is that every point on a wavefront is itself the source of spherical wavelets, and the secondary wavelets arising from different points mutually interfere. The total of these spherical wavelets forms the wavefront. In this article, we will discuss the Huygens wave theory of light and Huygens Principle Derivation. 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:
