Here figure A shows the proper phase relationship of an incident and reflected wave from the interference of two materials where n2<n1.
Upon reflection from a boundary between two transparent materials, the phase of the reflected light may change.
If n1> n2 - - - no phase change upon reflection.
If n1< n2 - - - phase change of 180o upon reflection.
