19. We use the lens maker’s equation, Eq. 35–10: 1 f =( n − 1) µ 1 r 1 − 1 r 2 ¶ where f is the focal length, n is the index of refraction, r 1 is the radius of curvature of the Frst surface encountered by the light and r 2 is the radius of curvature of the second surface. Since one surface has twice the radius of the other and since one surface is convex to the incoming light while the other is
