A real image is an image that is formed by the actual intersection of light rays. It is formed when light rays converge at a point after reflecting off a concave mirror. The image is inverted and can be projected onto a screen. A virtual image, on the other hand, is an image that appears to be located at a point behind the mirror. It is formed when light rays appear to diverge from a point behind the mirror after reflecting off a convex mirror²³.

I hope this helps! Let me know if you have any more questions.
