List four characteristics of the image formed by a plane mirror.

A plane mirror forms images with the following four characteristics:

Virtual Image: The image formed by a plane mirror is virtual, meaning it is not a real image that can be projected onto a screen. Instead, it appears to be behind the mirror's surface.

Upright and Unchanged in Size: The image in a plane mirror is upright (not inverted) and is the same size as the object. It preserves the size and orientation of the object.

Laterally Inverted: The image is laterally inverted, which means left and right are reversed compared to the object. For example, if you raise your right hand in front of a plane mirror, it will appear as if your left hand is raised in the mirror image.

Same Distance as the Object: The image appears to be located at the same distance behind the mirror as the object is in front of it. This is in accordance with the law of reflection, which states that the angle of incidence (the angle at which light strikes the mirror) is equal to the angle of reflection (the angle at which light is reflected off the mirror).
