A virtual image is created by the apparent intersection of the reflected light rays.
A virtual image cannot be obtained on the screen.
Explanation:
Illusion is similar to virtual images.
The rays meeting to form a virtual image are simply an extension of reflected rays, where the rays never actually meet and thus cannot be obtained on the screen.
A virtual image is an upright image that is achieved where the rays seem to diverge.
A virtual image is produced by the use of a diverging lens or a convex mirror.
A virtual image is found by tracing real rays that emerge from an optical device backward to perceived or apparent origins of ray divergences. As the rays never really converge, a virtual image cannot be projected onto a screen.
So a virtual image cannot be obtained on the screen.
