(a) In each case, a key is placed in front of a converging lens so that an inverted image of the key is formed on the other side of the lens. (The object distance is greater than the focal distance.) The two cases are identical except that the key and lens are in air in Case A and in water in Case B. Is the distance from the lens to the image of the key (the image distance) (i) greater in Case A, (ii) greater in Case B, or (iii) the same in both cases? Explain your reasoning. b) In each case, a key is placed in front of a converging mirror so that an inverted image of the key is formed on the same side of the mirror. (The object distance is greater than the focal distance.) The two cases are identical except that the key and mirror are in air in Case A, and in water in Case B. Is the distance from the lens to the image of the key (the image distance) (i) greater in Case A, (ii) greater in Case B, or (iii) the same in both cases?
