What term describes the image formed by a plane mirror that cannot be projected on a screen but can be seen in the mirror?

Explanation:
The main idea is that plane mirrors create a virtual image. When light reflects off a plane mirror, the rays appear to come from a point behind the mirror, but they don’t actually meet there. Because the rays don’t converge in real space, the image can’t be projected onto a screen. You can still see it clearly by looking into the mirror, and it looks upright and the same size as the object. That combination—visible in the mirror but not projectable—defines a virtual image. In contrast, a real image would be formed by converging rays that actually meet in space and could be projected, and an inverted image would be upside down, which isn’t characteristic of a plane mirror.
