Many outdoor athletes splurge on a high-end pair of sunglasses. The lenses in these glasses are not a single piece of glass, but are actually composed of multiple layers (see the photo). The antireflective coating at the back of the lens is there to reduce back glare, which is light that strikes the back of the lens and reflects toward the eyes. The antireflective coating consists of a transparent thin film with an index of refraction equal to 1.36. The film, with a thickness of 96.0 nm, is applied to the back of the glass lens, which has an index of refraction of 1.52. Which wavelength of light in the visible spectrum is not reflected from the coating, due to destructive interference?
