Figure P36.40 shows a thin glass (n = 1.50) converging lens for which the radii of curvature are R1 = 15.0 cm and R2 = -12.0 cm. To the left of the lens is a cube having a face area of 100 cm2 . The base of the cube is on the axis of the lens, and the right face is 20.0 cm to the left of the lens.
(a) Determine the focal length of the lens.
(b) Draw the image of the square face formed by the lens. What type of geometric figure is this?
(c) Determine the area of the image.
