A virtual image is defined as an image formed by the apparent intersection of diverging light rays, which cannot be projected onto a screen. This occurs because the light rays appear to come from a position where they do not physically converge.

In systems such as a flat mirror or a diverging lens, when light rays collide with the surface, they reflect or bend in such a way that they appear to originate from a point behind the mirror or lens. This creates the illusion of an image that cannot actually be captured or projected onto a screen because the rays do not actually meet at a tangible location.

In contrast, the other choices describe various aspects of image formation. An image formed by the interception of converging light rays typically results in a real image, which can indeed be displayed on a screen, which does not align with the definition of a virtual image. Real images are formed when light rays actually converge. The notion of an image that can be displayed on a screen pertains to real images, further differentiating them from virtual images. Lastly, an image created solely by reflections does not encompass virtual images fully, as they can also be formed by refraction. Thus, understanding that virtual images arise specifically from the perception of diverging light is key in
