White light reflects off of a thin layer of MgFy on glass. The MgF film has an index of refraction of 1.39, and the glass has an index of refraction of 1.50. Part A What is the wave shift for light that reflects at the air-to-MgF interface? The wave shift is OA O The wave shift is A/2. Submit Request Answer Part B What is the wave shift for light that reflects at the MgF-to-glass interface? O The wave shift is A/2. The wave shift is OA Submit Request Answer Part C What is the thinnest film of MgFy on glass that will produce a strong reflection (i.e. constructive interference) for orange light with a wavelength of 625 nm? In other words, when white light shines on the surface of the thin film, the reflected light is orange.
