Mirror imageThe mirror image of an object or two-dimensional figure is the virtual image formed by a plane mirror; it is of the same size as the original object, yet different, unless the object or figure has mirror-image symmetry (also known in the terminology of modern physics as a P-symmetry). The concept of mirror image can be extended to three-dimensional objects, including the inside parts, even if they are not transparent. The term then relates to structural as well as visual aspects. For example, the left hand is the mirror image of the right hand.Examples:
A mirror image of a two-dimensional figure is also obtained when looking at it from the other side, in the case that the figure can still be seen from there. This may be the case due to transparency, or if the coloring isn't just at the surface but also inside, or if a shape has been cut out. Examples:
The mirror-image of a mirror image is a regular image. When you see a reflection that surprisingly is a regular image this is usually caused by the fact that you are looking at the reflection of a reflection, or the reflection of an image seen from the other side (see above). On sunny days perhaps the most common example of the latter is seeing the reflection in a window of the inside of a parasol with text on it. Occasionally you can see a mirror image, even though you are aware of looking at the reflection of a reflection; this may be due to a third reflection. A text is sometimes displayed in mirror image on the front side of a car, to be seen as a regular text in the rear view mirror of the car in front.
