MATRIX MATCH TYPE

10.    Column I shows four situations of standard Young's double slit arrangement with the screen placed far away from the slits S₁ and S₂. In each of these cases S₁P₀ = S₂P₀, S₁P₁ - S₂P₁ = λ/4 and S₁P₂ - S₂P₂ = λ/3, where l is the wavelength of the light used. In the cases B, C and D a transparent sheet of refractive index m and thickness t is pasted on slit S₂. The thickness of the sheets are different in different cases. The phase difference between the light waves reaching a point P on the screen from the two slits is denoted by δ(P) and the intensity by I(P). Match each situation given in Column I with the statement(s) in Column II valid for that situation.

Sol.   (A ->p, s); (B -> q); (C -> t); (D -> r, s, t)
