What type of image is produced by a concave lens?

A concave lens always produces a virtual, upright, and diminished image. This occurs because a concave lens diverges light rays that are incident upon it. When parallel rays of light pass through a concave lens, they spread outwards, making it seem as though they are originating from a point behind the lens.

Since the light rays do not actually converge, the image cannot be projected onto a screen, leading to its classification as a virtual image. Furthermore, the image created is upright, meaning it maintains the same orientation as the object, and diminished, indicating that it appears smaller than the actual object. This behavior is fundamental to the properties of concave lenses and is consistently observed across different scenarios involving such lenses.
