A real image can be formed on the screen when light beams from an object meet, either after reflection or refraction.
Light rays from a virtual image from objects that do not meet but appear to meet when produced backward. These images are not visible on the screen.
The real image is always reversed. The virtual image is always upright.
When the light rays from the object coincide with each other either after undergoing reflection or refraction, the real image will appear on the screen.
Therefore, a real image can be obtained on the screen.
