Question

For the magnification of an image to a be positive value, where must the object be in relation to the focal length?

A. s > 2f

B. 2f > s > f

C. s < f

Answer 1

As for concave lens and convex mirror the magnification is always positive while we are doing this answer for concave mirror and convex lens.

The Correct choice is (C) s<f

Explanation:- When the object is located at a location in front of the focal point, the image will always be located somewhere on the same side as the object. Regardless of exactly where in front of F the object is located, the image will always be located on the object's side of the concave mirror/convex lens.
