A real image is formed when light rays converge at a point after passing through a lens or reflecting from a mirror. It can be projected onto a screen as the light actually passes through the image location.

A real image is always inverted relative to the object.
The formation of a real image requires that the object be placed outside the focal length of the lens or mirror.
Real images can be captured on photographic film or sensors since they are formed by actual light rays converging.
The size and position of a real image can be determined using lens/mirror equations like $\frac{1}{f} = \frac{1}{d_o} + \frac{1}{d_i}$, where $f$ is the focal length, $d_o$ is the object distance, and $d_i$ is the image distance.
In optical systems, real images are typically formed by converging lenses (convex) or concave mirrors.
