Concave and Diverging
Smaller
For apex learning people the answer is diverging
Diverging mirrors and lenses always produce virtual images that are upright and smaller than the object being viewed.
Diverging lenses do not always produce smaller images; they typically create virtual images that are upright and smaller than the object when the object is placed at any distance from the lens. However, the perceived size of the image can vary based on the object's distance from the lens and the specific characteristics of the lens itself. In general, diverging lenses are known for making images appear smaller than the actual object.
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.
Concave lenses can produce either smaller or larger images, depending on the object's distance from the lens and the characteristics of the lens itself. The image produced by a concave lens can be virtual, upright, and smaller, or it can be real, inverted, and larger.
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 lenses produce virtual, upright, and smaller images of objects placed beyond their focal point. These images are formed on the same side as the object, making them virtual in nature.
Convex lenses always form smaller, virtual images
Concave D. Diverging
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.
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.
