Transmission through 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.) Part of the light ends up in material 3 as ray ra (the light does not reflect inside
material 2) and ra (the light reflects twice inside material 2). The waves of r3 and r4interfere, and here we consider the type of
interference to be either maximum (max) or minimum (min). The table below provides the indexes of refraction n1, n2, and n3, the type
of interference, and the thinlayer thickness L in nanometers. Give the wavelength that is in the visible range.
