A wide-angle mirror producing reduced virtual images to discourage shoplifting is a:
plane mirror
O concave mirror
convex mirror

The correct answer is convex mirror

Convex Mirror

Characterized as being a spherical mirror, and can be considered for any external surface in the form of a spherical cap that is capable of reflecting the incident light, that is, the convex mirror is a “slice” of a sphere, that slice it is called a spherical cap, and therefore known as a spherical mirror, and the part that reflects (polished) is the outer part of this cap. Below is an image that illustrates the formation of two spherical mirrors, one on the outer part of the shell and another on the inner part.

Commonly, convex mirrors are used to “prolong” the vision, so we can see angles reflected by them that we would not be able to see using flat mirrors for example. With that it is said that such mirrors allow to enlarge the field of vision.
