Web8 Nov 2024 · When light strikes a thin film with air on both sides, if the film allows for no light to be reflected (i.e. all the reflected light destructively interferes), then conservation of energy requires that all of the light passes through the film to the other side. WebIn thin-film interference, light waves reflect of the front and back surfaces of a transparent thin-film. The two primary reflected waves interfere, sometimes constructively. Use the sliders or input boxes to adjust the index of refraction of the material in front of the thin film, the thin film, and the material behind the thin film, as well as the thickness of the thin film …
