    **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?

    It is correct.
    "Repeating pattern" is fine.

    Look at this link

    https://www.google.com.au/?gfe_rd=c...rror+virtual+image&biv=i|11;d|ghfxmbJIYCyg6M:

    See how the lines are drawn. See where the virtual image is drawn. Use the outside lines in your original picture as a guide to drawing your virtual images. These lines would not be there in the problem for no reason.

    I would suggest it is probably not highly regarded to start multiple threads for the same problem.

    I must retract part of that post, you have included different points in the problem. Although I don't think that eithere of the arrows are shown in a very good direction to see a repeating pattern. You are going to be looking at the floor within two reflections at most it would seem...

    I think the arrows are copied from the original sketch, an represent the real box.
