Suppose the absolute values of the radii of curvature of the lens surfaces in Fig. are both equal to 10 cm and the index of refraction of the glass is n = 1.52. What is the focal length f of the lens? (b) Suppose the lens in Fig2 also has n = 1.52 and the absolute values of the radii of curvature of its lens surfaces are also both equal to 10 cm. What is the focal length of this lens?
