Timer Feedback Peter The lens material is CR-39 monomer, with an index of refraction of 1.499. Calculate R, the radius of curvature of the outer surface for the lens. Note: the diopter is a measure of the refractive power of a lens, and equals the reciprocal of the focal length in meters. (Examples for +3 diopters, f-0.333 meters.) Tres 0/12
