Theory: Thin Film Interference • Start at the beginning: is an equation for d3 to plug in the data collected and compare to d2 index of refraction.

The interference produces a pattern of beautiful colors in white light, or dark and light bands in monochromatic light. How it works: Our two most visually dramatic illustrations of thin film interference use either a soap film suspended in air from a 19 cm diameter circular frame, or a very thin layer of oil floating on top of water. This article will focus on one particular form of interference, namely thin film interference. This occurs when one or more very thin transparent coatings ("films") are placed on top of a material. 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.

Thin films The reflection intensity from a soap film for light of a given wave length can be this formula (source is Cyril Isenbergs great book, "The Science of Soap films and Soap The graph below illustrates how the interference of one Nov 4, 2020 When waves that have the same wavelength interfere with each other, the difference in the distances they've traveled Thin Film Interference. Thin-film optical filters are made by depositing alternating layers of materials onto a Depending on the wavelength and filter design, light can be reflected off of the as it passes from one layer to the next, resulting in interna quicky about interference colors from oil films (or any other transparent thin film ). An incoming wave with wavelength λR hits the liquids at an angle α and is  interference pattern is produced. λ = wavelength of light.

When the thickness of the film is an odd multiple of one quarter-wavelength of the light on it, the reflected waves from both surfaces interfere to cancel each other. Since the wave cannot be reflected, it is completely transmitted instead.
