Define a real image.

A real image is defined as one that is formed by the actual intersection of light rays, meaning that the light rays converge at a point after passing through a lens or reflecting off a mirror. This characteristic allows the real image to be projected onto a screen, as the light rays physically meet and produce a visible representation.

When light rays from an object pass through a converging lens or reflect off a concave mirror, they come together at a point that is the location of the real image. This type of image is typically inverted relative to the object due to the way light travels and is processed by the optics involved.

In contrast, options discussing diverging light rays or those that cannot be projected onto a screen do not describe the nature of a real image. A real image is distinct from virtual images, which cannot be displayed on a screen because the light rays do not actually converge but appear to diverge from a point behind the lens or mirror. Additionally, real images are not characterized by being consistently upright, as they can be inverted depending on the arrangement of the optical elements used.
