Reflection by thin layers. In the figure, light is incident perpendicularly on a thin layer of material 2 that lies between (thicker) materials 1 and 3. (The rays are tilted only for clarity.) The waves of rays r, and rz interfere, and here we consider the type of interference to be either maximum (max) or minimum (min).
