Question: what is the relationship between the object distance from the lens and the image magnification?
Answer: The closer the object to the focal pointis, the higher is the magnification rate. If the object is placed 2X of the focal length, then the object and the real image will have the same size. If the objet´s distance is farther than 2X-focal lenth, then the real image becomes demagnified – is smaller than the object.
