43. Consider the interference of waves reﬂected from the top and bottom surfaces of the air Flm. The wave reﬂected from the upper surface does not change phase on reﬂection but the wave reﬂected from the bottom surface changes phase by π rad. At a place where the thickness of the air Flm is L , the condition for fully constructive interference is 2
