Multiplechoice questions may continue on the next column or page find all choices before answering. 001 (part 1 of 2) 10.0 points The left face of a biconvex lens has a radius of curvature of 10 . 3 cm, and the right face has a radius of curvature of 21 . 5 cm. The index of refraction of the glass is 1 . 44. Calculate the focal length of the lens. An swer in units of cm. 002 (part 2 of 2) 10.0 points Calculate the focal length if the radii of curva ture of the two faces are interchanged. Answer in units of cm. 003 (part 1 of 2) 10.0 points Two converging lenses, each of focal length 14 . 3 cm, are placed 39 . 1 cm apart, and an object is placed 29 . 6 cm in front of the first. How far from the first lens is the final image formed? Answer in units of cm. 004 (part 2 of 2) 10.0 points What is the magnification of the system?...
