1. A converging lens has a focal length of 20.2 cm.
(a) Locate the object if a real image is located at a distance from the lens of 40.4 cm.
(b) Locate the object W a real image is located at a distance from the lens of 101.0 cm.
(c) Locate the object if a virtual image is located at a distance from the lens of -40.4 cm.
(d) Locate the object W a virtual image is located at a distance from the lens of -101.0 cm.
2. The left face of a biconvex lens has a radius of curvature of magnitude 11.7 cm, and the right face has a radius of curvature of magnitude 19.6 cm. The index of refraction of the glass is 1.52.
(a) Calculate the focal length of the lens for light incident from the left.
(b) After the lens is turned around to interchange the radii of curvature of the two faces, calculate the focal length of the lens for light incident from the left.
