1. The problem statement, all variables and given/known data Please note that this is an extension of this question here: https://www.physicsforums.com/showthread.php?p=4571995#post4571995 **Questions** Mirrors A and B with the space between them, including the bird, are part of the real world. Those are all a part of a basic cell. The space between A and B' (including the mirrored bird) is the mirror image (in mirror A) of the basic cell. This is a virtual cell space. we call this a virtual cell. 1. Add more virtual cells (mirror images of mirrors and repeats thereof) with birds in them. 2. Which structure or pattern do you discover in the of cells? 2. Relevant equations mirror reflection 3. The attempt at a solution 1. Is this the correct way to do mirror reflection? You have to keep in mind that " If look at a mirror from the same direction and angle as one of the two arrows that are drawn, you will see the bird in the mirror." from the question here: https://www.physicsforums.com/showthread.php?p=4571995#post4571995 2. I do see this repeating patterns, but I do not whether this has a specific name or not. Does somebody have a good way to describe it?
