Question

In case of a real and inverted image, the magnification created by the mirror is

• A. positive
• B. negative
• C. unity
• D. Infinity

Answer 1

The correct option is B negative

Magnification of image created by mirror is defined as
$m=\frac{sizeofimage}{sizeofobject}$
and in case of inverted image. Size of image is negative whereas size of object is positive. Hence , magnification produced is negative and it can be unity when object is placed at center of curvature and infinity when object is at focus.
