Question

For a real image formed by a convex lens, the ratio of I : O = 2 : 5, then the object is ______.
(I is the height of the image and O is the height of the object)

Options

• between O and F

• beyond 2F

• at F

• between F and 2F

Answer 1

For a real image formed by a convex lens, the ratio of I : O = 2 : 5, then the object is beyond 2F.

Explanation:

Since the picture is smaller than the object, the item must be positioned beyond 2F for a convex lens.
