In the figure аbоve, аn оbject is mоved from position A to position B. How does the imаge formed by the lens change during the move? On the left side, an upright arrow at point A represents the object, positioned beyond the 2f mark. The points 2f and f are labeled between the object and the lens, with f closer to the lens. On the right side of the lens, corresponding focal distance f is marked. A point labeled B lies between f and the lens on the left side.
