Question

Why is it difficult to generate a virtual image on a screen? How can we comprehend it practically?

Answer 1

Formation of virtual image:

1. A virtual image is described as the opposite of a real image; hence, a virtual image is one that cannot be obtained on a screen.
2. A virtual image can't be acquired on the screen for it is caused by light rays that don't meet but appear to meet at a moment when the rays are created backward.
3. The resultant virtual picture is never reversed and is always upright. To comprehend the notion, simply stand in front of a mirror. The imagined and upright image formed by the mirror is always present.
