Question

can you find the minimum limiting object distance from a real image by a convex lens? how?​

Answer 1

Answer:

Let, d be the distance between the image and the object. If the image distance from the lens is x, the object distance from the lens will be (d – x). Thus, u = – (d – x) and v = + x. Hence, 4f is the minimum distance between the object and its real image formed by a convex lens.
