http://electron9.phys.utk.edu/optics421/modules/m5/Interferometers.htm WebbOne application of interference is reflection from a thin film, where the interference is between light reflected at the top and at the bottom of the film, as shown in Figure 1. For light incident perpendicular to the film (normal incidence), the path difference for the two rays 1 and 2 is 2t, where t is the thickness of the film. Figure 1.
