Question

what is the differences between virtual and real images?​

Answer 1

Answer:

To obtain a real image the light source and the screen must be placed on the same plane. Real images are obtained using a converging lens or a concave mirror. The size of the real image depends upon the placement of the object.

A virtual image is an upright image that is achieved where the rays seem to diverge. A virtual image is produced with the help 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. Because the rays never really converge, a virtual image cannot be projected onto a screen.
