The magnitudes of the radii of curvature are 30.5 cm and 44.2 cm for the two faces of a biconcave lens. the glass has index of refraction 1.53 for violet light and 1.51 for red light. (a) for a very distant object, locate the image formed by violet light. (give your answer to two decimal places. indicate the position of the image relative to the lens with the sign of your answer.) (b) for a very distant object, locate the image formed by red light. (give your answer to two decimal places. indicate the position of the image relative to the lens with the sign of your answer.)
