The phase shift upon reflection is λ / 2
WebbOil Film Interference. The interference colors from an oil film on water can be related to the thickness of the film by using the interference condition and noting that there is a 180 degree phase change upon reflection from the film surface, but no phase change for the reflection from the back surface. This presumes that the index of refraction of the oil is … WebbQuestion regarding the phase shift or path difference of λ/2 when light gets reflected off of a denser medium.
