A flat surface that provides an upright visual picture of a genuine item when the front and rear are flipped is called the plane mirror.
Images created by plane mirrors are the reflected image in their typical dimensions but are reversed from left to right. These are the most often used mirrors.
The object's distance would be the same as the image's distance from the plane mirror.
The image's size would be the object's size.
Hence, the image generated by a plane mirror is always imaginary and erect.
