Question

An object of size 12 cm is placed in front of a concave mirror, it forms a real and inverted image of size 18 cm. What is the magnification of the image?

  1. 1.75
  2. -1.75
  3. 1.5
  4. -1.5

hintHint:

-1.5

The correct answer is: -1.5


    m=image size/object size
    For a real and inverted image, the magnification of the mirror is negative.
