Question

If the magnification is positive and greater than unity, what does it indicate?

(a) Virtual image

(b) Real image

(c) Distorted image

(d) Erect image

Answer 1

Right answer is (a) Virtual image

The explanation is: For virtual image, the magnification is positive and greater than unity.

Since, m = h2/h1 = length of image / length of object = distance of image / distance of object

For real image, the magnification is negative.
