A very thin sheet of plastic covers one slit of a double-slit apparatus illuminated by 680-nm light. The centre point on the screen, instead of being a maximum, is dark. What is the (minimum) thickness of the plastic? (The refractive index of the plastic cover is 1.60)

Laser light of wavelength 627.0 nm passes through a double-slit arrangement at the front of a lecture room, reflects off a mirror 29.2 m away at the back of the room, and then produces an interference pattern on a screen at the front of the room.
