(a) in position,
(b) in size? If yes, describe how.
参考答案: (a) Yes, as a thin converging lens is moved closer to a nearby object, the position of the real image changes. In this situation, the object distance decreases and the thin lens equation says that the image distance increases. Thus, the position of the image moves farther away from the lens. (b) Yes, as a thin converging lens is moved closer to a nearby object, the size of the real image changes. In this situation, the object distance decreases and the thin lens equation says that the image distance increases, which means that the magnification(m = $-d_1$/$d_o$) gets larger. Thus, the size of the image increases.
