A concave mirror, or converging mirror, has a reflecting surface that bulges inward (away from the incident light). Concave mirrors reflect light inward to one focal point.They are used to focus light. Unlike convex mirrors, concave mirrors show different image types depending on the distance between the object and the mirror.
These mirrors are called "converging" because they tend to collect light that falls on them, refocusing parallel incoming rays toward a focus. This is because the light is reflected at different angles, since the normal to the surface differs with each spot on the mirror.
Distance from the mirror, curvature of the mirror.
A concave mirror is dished in ward. A convex mirror domed. Both images will be distorted in size from actuality. A convex mirror will give a wider view of what you are looking at in the mirror. A concave mirror will compress and magnify the image being viewed.
A concave mirror can show both virtual and real images. The type of image produced depends on the position of the object relative to the focal point of the mirror.
An image produced by a convex mirror and an image produced by a concave lens are both virtual, erect, and diminished. They both form on the same side as the object and the images appear smaller than the object itself.
If an object's distance from the concave mirror is greater than the mirror's focal length, then the mirror image of it will be inverted. If the distance from the concave mirror is less than the focal length of the mirror, the image will not be inverted. No image will be produced if the distance from the mirror to the object is equal to the mirror's focal length.
A concave mirror can produce a real or virtual image, depending on the location of the object. Real images are formed in front of the mirror and can be projected onto a screen, while virtual images are formed behind the mirror and cannot be projected. The characteristics of the image, such as magnification and orientation, are determined by the mirror's focal length and the object's distance from it.
Some images on a mirror usually appear erect because of the concave mirror.
A convex lens is more like a concave mirror in the way it produces images. A convex lens converges light rays to form real or virtual images, much like how a concave mirror can do the same by reflecting light. Both convex lenses and concave mirrors can produce both real and virtual images depending on the object's position relative to the lens or mirror.

The concave mirror focusses images to its focal point. So the images formed are real inverted and increases in size as the distance between the aperture and the object decreases. When the object is placed between the focus and the aperture the image formed is virtual erect and magnified.
A plane mirror produces an upright and laterally inverted image that is the same size as the object. A concave mirror produces a real or virtual, inverted or upright image that can be larger or smaller than the object depending on the object's position relative to the mirror. A convex mirror produces a virtual, upright, and smaller image compared to the object, regardless of the object's position relative to the mirror.
