Question
What is a virtual image?
✓

Answer

  1. The image that cannot be caught on a screen.
Explanation:
When the actual rays diverge then they can never meet to form an image. Therefore the rays are assumed to meet in the backward direction of their propagation. 
As the imaginary light rays meet and form the image, therefore the image can not be caught on a screen.
