Q. Why the centre of Newton's rings pattern appears dark?
The thickness of the air film becomes zero at the point of contact of lens L with glass plate P. Therefore there is no path difference between the interfering waves. So it must appear bright. However the wave reflected from the denser glass plate has suffered a phase change of π while the wave reflected at the spherical surface of the lens has not suffered any phase change. Therefore the point O appears dark.
