Let’s consider a dark ring with radius r at a point where the separation is t. The right angled triangle shown in red has a height R–t so Pythagoras’ theorem gives us. Newton’s rings Aim of the experiment: To observe Newton rings formed by the interface of produced by a thin air film and determine the radius of curvature of a plano-convex lens.
