Conclusion
A plane mirror forms a virtual, upright image of equal size to the object. The image distance equals the object distance.
Rule 1
Image distance equals object distance (v = u). The image appears as far behind the mirror as the object is in front.
Rule 2
Image size equals object size (M = 1). The image is the same size as the object, upright and laterally inverted.
