The sketch shows a light ray traveling through a thin layer sandwiched between two media. The indices of refraction of the media are such that there is a 180° phase shift between the incoming and the reflected
waves at the interface between media 1 and 2, but no phase shift between the incoming and the reflected
waves at the interface between media 2 and 3. (Note: This does not necessarily agree with the answer to the
previous question.) The index of refraction of the thin layer is n2 = 1.182 and the thickness of the thin layer is
325.7 nm. What are the longest and next longest wavelengths that are optimally transmitted by the thin
layer?
