The radius of curvature of the convex surface of a plano-convexlens is 200 cm. The lens is placed convex side down on the concavesurface of a plano concave lens as shown below. The radius ofcurvature of the concave surface is 400 cm. The lenses areilluminated from above with red light of wavelength 633 nm (HeNelaser). Find the diameter of the third bright ring in theinterference pattern seen by reflected light.
Im not sure what equations to use for this problem, any help wouldbe really appreciated, thanks
