WebMay 19, 2024 · Considering that the section of the ray tube increases with the increasing distance, which would affect the accuracy of ray tracking. Therefore, the wavefront division of the regular dodecahedron is necessary as shown in Figure 3b. Each equilateral triangle is uniformly divided into N wave fronts. 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.
