Solution
Concave mirror only.
Explanation:
A concave mirror can form a real image when the object is placed at a distance greater than the focal point of the mirror. The real image formed by a concave mirror is inverted and can be projected onto a screen.
-
A plane mirror always forms a virtual, upright image, not a real image.
-
A convex mirror always forms a virtual, diminished image, not a real image.
