Question

A negative magnification indicates that the image is:

• A. Inverted
• B. Erect
• C. Diminished
• D. Enlarged

Answer 1

The correct option is A Inverted

We know that magnification, $m=\frac{h_i}{h_o}$.
Magnification is negative, hence, according to the convention, the height of the image and the height of the object have opposite signs i.e., an inverted image.
An inverted image is always real for a mirror and a lens. Therefore, a negative magnification further indicates that the image is real and inverted.
