Two transparent slabs having equal thickness but different refractive indices mu subscript 1 end subscript and mu subscript 2 end subscript are pasted side by side to form a composite slab. This slab is placed just after the double slit in a Young's experiment so that the light from one slit goes through one material and the light from the other slit goes through the other material. What should be the minimum thickness of the slab so that there is a minimum at the point P subscript 0 end subscript which is equidistant from the slits?
