A point sources
S emitting light of wavelength
600 nm is placed at a very small height
h above a flat reflecting surface
AB (see figure). The intensity of the reflected light is
36% of the incident intensity. Interference fringes are observed on a screen placed parallel to the reflecting surface at a very large distance
D from it.Calculate the ratio of the minimum to the maximum intensities in the interference fringes formed near the point
P (shown in the figure).
