Figure P23.59 shows a converging lens with radii R 1 = 9.00 cm and R 2 = 211.00 cm, in front of a concave spherical mirror of radius R = 8.00 cm. The focal points ( F 1 and F 2 ) for the thin lens and the center of curvature ( C ) of the mirror are also shown. (a) If the focal points F 1 and F 2 are 5.00 cm from the vertex of the thin lens, what is the index of refraction of the lens (b) If the lens and mirror are 20.0 cm apart and an object is placed 8.00 cm to the left of the lens, what is the position of the final image and its magnification as seen by the eye in the figure (c) Is the final image inverted or upright Explain.
