A thin plastic sheet of refractive index 1.6 is used to cover one of slits of a double slit arrangement for the Young’s experiment. When the double slit is illuminated by monochromatic light (wavelength = 5867 A) the centre of the screen appears dark rather than bright. The minimum thickness of the plastic sheet to be used for this to happen is
