WebJun 21, 2024 · 3.1: Cornu's Spiral. If a parallel beam of light from a distant source encounters an obstacle, the shadow of the obstacle is not a simple geometric shadow but is, rather, a diffraction pattern. For example, it is … Webfollows that there exists a shadow region D (see Figure 1) in which the intensity of waves is zero. This region is separated from the region A, reached by incident and reﬂected rays, by a surface called the shadow boundary. Obviously, along this boundary the solution obtained by the ordinary geometrical optics method is discontinuous.

The umbra (Latin for "shadow") is the innermost and darkest part of a shadow, where the light source is completely blocked by the occluding body. An observer within the umbra experiences a total occultation. The umbra of a round body occluding a round light source forms a right circular cone. When viewed from the cone's apex, the two bodies appear the same size. Webgeometric shadow.
