Two flat glass plates are separated by a distance d = 115 nm. There is a layer of oil between the plates. White light shinesdirectly down on the glass. One ray reflects off the top surface of the top oil layer, and a second ray reflects off the bottomsurface of the oil layer. The index of refraction of the glass is n, = 1.63, and the index of refraction of the oil is n. = 1.33.glassoilglassa. For each ray state whether there is a ½2 phase change, or no phase change.
