Virtual Image : 1 Mark
When : 2 Marks

When an image cannot be obtained on a screen, it is called as virtual image.

A virtual image is an image formed when the outgoing rays from a point on an object always diverge. The image appears to be located at the point of apparent divergence. Because the rays never really converge, a virtual image cannot be projected onto a screen.
