Question

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

• A. 1/2
• B. 2
• C. -2
• D. -1/2

Answer 1

Answer:

C. -2

• 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.
