Question

A real object is kept at a distance of 2f, first in front

of a convex lens and then in front of a concave

mirror, each having focal length f. The ratio of

magnifications produced by them will be

Answer 1

Answer:

1:1

Explanation:

if we take 0.5 m as focal length then 2f is 1m and if we calculate v in both cases ( in concave and convex) by sign convention the ratio is 1:1
