A plan convex lens with radius of curvature R =3.4 m is in contact by a flat plate of glass. A light source and the observer's eye are both close to the normal, as shown in Figure 24.8a. The radius of the50th bright Newton's ring is found to be 9.1 mm. What is the wavelength of the light produced with the source?
