A biconcave lens has radii of curvature equal to R, = 30.4 cm and R, = 42.3 cm. A very distant object on the R, side of the lens forms an image. The lens medium has index of refraction 1.53 for violet light and 1.51 for red light. (a) Where is the image formed by violet light? (Enter your answer in cm and indicate the position of the image relative to the lens with the sign of your answer. Give your answer to at least two decimal places.) cm (b) Where is the image formed by red light? (Enter your answer in cm and indicate the position of the image relative to the lens with the sign of your answer. Give your answer to at least two decimal places.) cm
