List 1 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 = lambda/4 and S1P2 - S2P2 = lambda/3 , where lambda is the wavelength of the light used. In the cases B, C and D , a transparent sheet of refractive index mu and thickness t is pasted on slit S2 . The thicknesses of the sheets are different in different cases.
