When the object is located at the 2F point, the image will also be located at the 2F point on the other side of the lens. In this case, the image will be inverted (i.e., a right side up object results in an upside-down image). The image dimensions are equal to the object dimensions. A six-foot tall person would have an image that is six feet tall; the absolute value of the magnification is exactly 1. Finally, the image is a real image. Light rays actually converge at the image location. As such, the image of the object could be projected upon a sheet of paper.

Negative magnification typically occurs when the image produced by an optical system appears inverted relative to the object being viewed. This happens when the image is smaller than the object, indicating that the image is reduced in size relative to the object. Negative magnification is common in situations where a concave lens or diverging mirror is used.
These words can have different meanings depending on subject but in terms of visual (and typically keywords when dealing with 3d images): Convergence typically refers to the object a viewer is looking at. Divergence is when your eyes have to overcompensate for badly placed (usually by over-extending the pixel separation) stereo pairs of images to see one image. This can cause eye strain. Hope this helps a little

Diverging mirrors and lenses always produce virtual images that are upright and smaller than the object being viewed.
Diverging mirrors and lenses always produce virtual images that are upright and reduced in size. These images are located on the same side as the object being observed.
Diverging lenses produce virtual, upright, and diminished images for all object positions. The virtual image is located on the same side of the lens as the object and is always reduced in size. This is due to the diverging nature of the lens, which causes light rays to spread out.
Concave D. Diverging
A concave lens always produces smaller images for both real and virtual objects. This is due to the diverging nature of the concave lens, causing light rays to spread out and create an image that is smaller in size compared to the object.
A diverging lens can produce several types of images, depending on the location of the object relative to the lens. Typically, a diverging lens will produce a virtual, upright, and reduced image for objects placed beyond the lens' focal point.
Concave lenses, also known as diverging lenses, produce images that are reduced in size. These lenses cause light rays to diverge, resulting in an image that is smaller than the object being viewed.
A concave lens can produce images that are smaller than the object, whereas a convex lens can produce images that are larger than the object. This is due to the way light rays are refracted by the different shapes of the lenses.
A diverging mirror, also known as a concave mirror, is a mirror that curves inward. It diverges light rays that strike it, causing them to spread out. It forms virtual images that are upright and smaller than the object.
A diverging lens can produce both reduced and magnified real images, depending on the position of the object relative to the lens and the focal length of the lens. However, the most common case is for a diverging lens to produce a reduced real image.
Concave mirrors can produce virtual upright images that are smaller than the original object when the object is placed beyond the focal point of the mirror. This type of image is formed due to the behavior of light rays reflecting off the mirror surface and converging at a point.
A diverging lens produces virtual, upright, and diminished images for objects located at a distance further than the focal point of the lens. These images are formed on the same side as the object and cannot be projected onto a screen.
