Which of the following best describes a property of a plane mirror?

A plane mirror has a unique property characterized by how it reflects light. When an object is placed in front of a plane mirror, the image produced is always at the same distance behind the mirror as the object is in front of it. This means that, if you stand two meters away from the mirror, your reflection will appear to be two meters behind the mirror. This relationship results in an image that is laterally inverted (flipped horizontally) but not inverted in terms of height.

This property of reflecting images at the same distance is fundamental to how plane mirrors function. It allows for a realistic representation of the object, maintaining the size and proportions while providing a precise reversal in the lateral direction.

In contrast, other characteristics attributed to different types of mirrors or optical devices do not apply here. For instance, plane mirrors do not enlarge objects; they maintain the same size. Moreover, they do not create images that are rotated or distorted. Understanding these principles reinforces the specific behavior of plane mirrors in optics.
