What type of mirror produces an image that is upright and larger than reality when viewed up close?

A concave mirror is the type that produces an upright and enlarged image when an object is placed close to the mirror. This phenomenon occurs because a concave mirror converges light rays that hit its surface. When an object is located nearer than the focal point of the mirror, the reflected rays diverge, leading the brain to interpret them as originating from a virtual image behind the mirror. This virtual image appears larger and upright compared to the actual object.

In contrast, convex mirrors always produce images that are diminished and upright, making them useful for wide-angle viewing but not for enlarging images. Flat mirrors create images that are the same size as the object and are also upright, but they do not produce magnified images. Polarizing mirrors serve a different function by reducing glare and do not significantly alter the size of images.
