When-a wave or a pulse is reflected normally from the surface of a denser medium-back into the rarer medium- then tere is a phase difference of -x3C0- According-to electromagnetic theory When a light beam falls on-a boundary of two media- then one part of it will be reflected and other part-will be refracted- If refractive index of a medium- where the electromagnetic wave-is refracted- is greater than the medium incident- then phase of reflected ray-will be reverse with respect to the incident beam- As a result of which the-wave suffers a phase change of -x3C0-
