Question

Which of the following are virtual images?

i) The image formed by an image projector.
ii) The image formed by a plane mirror.
iii) The image formed by rear-view mirrors in automobiles.

Answer 1

Let's go through these one by one:

i) Projector works on the principle of image formation on a screen. So it can’t be a virtual image.
ii) Plane mirrors always form virtual and erect images.
iii) Rear view mirrors use convex mirrors(spherical mirrors) which also always form a virtual and erect image.

Therefore, the correct answer is option B, (ii) and (iii) only.
