There is a monochromatic light with wavelength λ = 529 nm shines down on a plano-convex lens lying on a piece of plate glass, shown in the figure below. When viewing from above, one sees a set of concentric dark and bright fringes. If the radius r of the 9th bright ring from the center is measured to be 0.256 cm, what is the radius of curvature of the lens?
