Fig. shows a surface XY separating two transparent media, medium 1 and medium 2. Lines ab and cd represent wavefronts of a light wave travelling in medium 1 and incident on XY. Line ef and gh represent wavefront of the light wave in medium 2 after rafraciton. The phase of the ligth wave at c, d, e, and f are phi_(c) , phi_(d), phi_(e) and phi_(f) , respectively. It is given that phi_(c ) != phi_(f) . Then
