A sheet that is made of plastic (n = 1.60) covers one slit of a double slit

Question:

A sheet that is made of plastic (n = 1.60) covers one slit of a double slit (see the drawing). When the double slit is illuminated by monochromatic light (Î»vacuum = 586 nm), the center of the screen appears dark rather than bright. What is the minimum thickness of theplastic?
