Question

To obtain a magnification of, –0.5 with a convex lens, the object should be placed
(a) at F
(b) between optical centre and F
(c) between F and 2F
(d) beyond 2F

Answer 1

To obtain a magnification of, –0.5 with a convex lens, the object should be placed (d) beyond 2F

Explanation:

Since the magnification is negative as well as less than 1 the created image is actual, inverted (An image created by reflection can be either real or virtual. When rays of light actually overlap at the picture, and become inverted or turned upside down, an "real" image occurs)  and decreased. The target should therefore be laid beyond 2F.

Therefore the correct answer is Option (d) beyond 2F
