WebWavefront. As a wavefront reaches the aperture, its propagation into the diffraction region is determined by the secondary waves emitted from all the various points on the aperture, and the wave disturbance at any point in the diffraction region is obtained by summation of the effects of the secondary waves. WebIt states that: “Every point on a wavefront is in itself the source of spherical wavelets which spread out in the forward direction at the speed of light. The sum of these spherical …
