R1 R2 R R infinity R R1 R2 Biconvex lens Equiconvex lens Plano convex lens Concavo convex lens R1 R2 R R infinity R R1 R2 Biconcave lens Equiconcave lens Plano concave lens Convexo concave lens You are designing a thin lens for use in a pair of glasses. You wish the design a Biconcave lens as shown in the figure. Using the data given below, determine the focal length (in cm) of the lens. Include negative signs as appropriate. (Example, if the lens is converging, your answer should be positive. If the lens is diverging, your answer should be negative.) • R1 = 4.347 cm • R2 = 2.630 cm • n = 1.980
