ransmission through thin layers. In the figure, light is incident perpendicularly on a thin layer of material 2 that lies between (thicker) naterials 1 and 3. (The rays are tilted only for clarity.) Part of the light ends up in material 3 as ray r3 (the light does not reflect inside naterial 2) and ra (the light reflects twice inside material 2). The waves of r3 and r4 interfere, and here we consider the type of nterference to be either maximum (max) or minimum (min). The table below provides the indexes of refraction n1, n2, and n3, the type- finterference, and the thinlayer thickness Lin nanometers. Give the wavelength that is in the visible range.
