WebbIt should be noted that the process of constructing a ray diagram is the same regardless of where the object is located. While the result of the ray diagram (image location, size, orientation, and type) is different, the same two rays are always drawn. The two rules of reflection are applied in order to determine the location where all reflected rays appear … WebbIf the film in Figure 3.12 is a soap bubble (essentially water with air on both sides), then a phase shift of λ / 2 λ / 2 occurs for ray 1 but not for ray 2. Thus, when the film is very thin and the path length difference between the two rays is negligible, they are exactly out of phase, and destructive interference occurs at all wavelengths. dynamic surroundings fabric 1.18
