Question
At which position will you keep an object in front of a convex lens so as to get a real image of the same size as the object? Draw a figure.
Solution
When an object is placed at the centre of curvature 2F1 of a convex lens, we will get a real image of the same size as the object.

A student has obtained an image of a distant object on a screen to determine the focal length F1 of the given lens. His teacher, after checking the image, gave him another lens of focal length F2 and asked him to focus the same object on the same screen.

(A) Concave and F1 < F2
(B) Convex and F1 < F2
(C) Convex and F1 > F2
(D) Concave and F1 > F2
