A convex lens forms a real and inverted image twice the size of the object. The magnification produced by the lens is equal to?

A1/2

B2

C-2

D-1/2

Answer:

C. -2

Read Explanation:

  • Magnification (m) is given by the ratio of image height (h') to object height (h).

  • Since the image is real and inverted, the magnification is negative.

  • Given that the image is twice the size of the object, m = -2.
