When a wave (light waves included) reaches the boundary between two media, a portion of the wave reflects off the boundary and a portion is transmitted across the boundary. PHY 2049: Chapter 36 14 Reflection and Interference from Thin Films ÎNormal-incidence light strikes surface covered by a thin film Some rays reflect from film surface Some rays reflect from substrate surface (distance d further) ÎPath length difference = 2d causes interference From full constructive to full destructive, depending on λ d n 1 n 2 n 0 = 1 This will affect the relative phase of the two light rays - the initially transmitted ray gets an additional phase Thicknesses on the order of 0.1 μm ~ 10 μm (¼λ ~ 10λ of visible light within the film) are considered "thin".Thin film interference can be both constructive and destructive. Summary  Thin film interference occurs when light reflects multiple times off the two sides of a thin transparent material. We reflect the wave from the two surfaces of a thin film. Light wave interference results when two waves are traveling through a medium and meet up at the same location. Perhaps you have witnessed streaks of color on a car windshield shortly after it has been swiped by a windshield wiper or a squeegee at a gas station. This is called division of amplitude. Thin-film interference. It can be seen in the above figure, that the original beam splits into two parts at the point B and they inter the eye after covering different lengths of paths. As the film is thin, so the separation between the beam BC and EF will be very small, and they will superpose and the result of their interference will be detected by the eye. I have been working on creating a Blender simulation for thin-film interference using the complex versions of the Fresnel and interference equations. The wavelength of the light is only equal to $\lambda/n_2$ within the thin film. Part of the implementation of the simulation includes reversing the order of the layers when we see backfacing geometry, such that the substrate becomes the medium and the medium becomes the substrate in the calculations. Interference of Light. This occurs when one or more very thin transparent coatings ("films") are placed on top of a material. Interference in Thin Films: Fig.1. When the medium through which a wave travels abruptly changes, the … The momentary streaks of color are the result of interference of light by the very thin film of water or soap that remains on the windshield. This article will focus on one particular form of interference, namely thin film interference. There is another way to make sure two interfering waves have the same polarization. The films are so thin that when a light wave comes into contact with these film layers, it reflects and refracts multiple times inside the layer system, and interferes with itself in the process. The interference occurs in the exterior region, where both wavelengths are $\lambda$.
