Question

Can a virtual image be formed on a screen?

Answer 1

Hint: In order to this question, to know whether a virtual image can be formed on screen or not, we have to go through the concept of the formation of image on any screen, and we will also explain the difference between virtual image and the real image.

Complete step by step solution:
A virtual image cannot be obtained on the screen because the virtual formed on the screen is due to the light rays that do not meet but appear to meet at a point when the rays are produced backward. The virtual image formed is always erect and is never inverted. To understand it practically just stand in front of a mirror. The image formed on the mirror is always virtual and erect.
A virtual image is an image obtained from the light rays from the object which do not meet and when produced backwards they appear to meet. A real image can be obtained on the screen. These images cannot be obtained on the screen. The real image is always inverted. The virtual image is always erect.

Real images	Virtual images
A real image can be obtained on the screen as the light rays coming from the object meet each other either after reflection or after refraction.	A virtual image is an image obtained from the light rays from the object which do not meet and when produced backwards they appear to meet.
A real image can be obtained on the screen.	These images cannot be obtained on the screen.
The real image is always inverted.	The virtual image is always erect.

Note:
Virtual images are formed when the light rays appear to be originating from a point but do not actually meet. It can be seen by human eyes. Hence, rear-view mirrors form virtual images. Real images can be seen on the screen. Virtual images cannot be formed on the screen. It is always erect. It is formed when rays of light appear to meet at a point.
