A concave mirror can produce an erect and enlarged image of an object, depending on the object’s position relative to the mirror. Specifically, when the object is placed between the focal point (F) and the mirror’s surface (closer to the mirror than its focal length), a concave mirror will produce an upright (erect) and magnified image. This type of image formation is useful in applications such as makeup mirrors and shaving mirrors, where an enlarged and upright reflection is desired.
