Interference in Thin Films - GSU
WebNewton's rings are interference patterns formed by light incident on the thin film of air between a convex lens and a flat (or between two suitable lenses). Here we explain the phenomenon and analyse its geometry. This … WebThe interference can be constructive, destructive, or something in between, depending on the thickness of the film. Note that, in the simulation, the incident wave is shown on top. The wave that reflects off the front surface of the film is moved below it, so we can see it easily without it being on top of the incident wave. In optics, a thin film is a layer of material with thickness in the sub-nanometer to micron range. As light strikes the surface of a film, it is either transmitted or reflected at the upper surface. Light that is transmitted reaches the bottom surface and may once again be transmitted or reflected. The Fresnel equations provide a quantitative description of how much of the light will be transmitted … iris and lilly knickers
