A double slit experiment is shown in the figure.
Each slit has width W. A thin piece of glass of
thickness δ refractive index µ, is placed between
one of the slits and the screen. The intensity at
the central point is measured as a function of
thickness δ. For what values of δ is the intensity
at C is minimum
