Is there any difference in both of these images?
Yes, there is a difference in image formation by the plane mirror and cinema screen. Let us see the differences in the tabular column given below.
Real image:
If the light rays from an object actually meet after reflection, the image formed will be a real image, which is always inverted. A real image can be captured on a sheet of paper or screen.
Virtual image:
A virtual image is created when light rays from an object do not actually meet but appear to meet when produced backwards. The virtual image is always upright and is impossible to capture on a screen.
Example for real image:
The image formed on the pin hole camera and cinema screen.
