WebThin Film Interference. The emphasis of Lesson 1 of this unit is to present some evidence that has historically supported the view that light behaves as a wave. The reflection, refraction and diffraction of light waves is one strand of evidence. The interference of light waves is a second strand of evidence. WebThin Film Interference Diversion: Coherence Length. Defined as the length in space over which the light has a predictable phase. A laser, for example, has a long coherence length. … WebThe proper way to define the conditions for having constructive or destructive interference requires knowing the distance from the observation point to the source of each of the two waves. Since there must be two waves for interference to occur, there are also two distances involved, R 1 and R 2. For two waves traveling in the same direction ... flip through book

"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 … " - How does thin film interference occur

WebExamine the situation to determine that interference is involved. Identify whether slits or thin film interference are considered in the problem. Step 2. If slits are involved, note that diffraction gratings and double slits produce very similar interference patterns, but that gratings have narrower (sharper) maxima.
