False

उत्तर
This statement is True.
Explanation:
In a concave mirror, the image formed is often inverted, meaning that the top and bottom or sides of the object and its image are interchanged. For example, if an object is placed in front of the mirror, its image will appear upside down (inverted) and may be laterally reversed (left to right), depending on the object’s position relative to the focal point. This is one of the typical characteristics of image formation by a concave mirror.
