Virtual cells of mirror reflections

Click For Summary

Homework Help Overview

The discussion revolves around the concept of virtual cells created by mirror reflections, specifically involving mirrors A and B and the images of objects (like birds) within these reflections. Participants are exploring the properties and patterns of these virtual cells.

Discussion Character

  • Exploratory, Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants are questioning the correctness of their understanding of mirror reflections and the identification of repeating patterns within the virtual cells. There is a request for clarification on how to describe these patterns effectively.

Discussion Status

Some participants have provided affirmations regarding the correctness of certain aspects of the problem. However, there are ongoing discussions about the clarity of the original setup and the appropriateness of the visual aids used to represent the reflections.

Contextual Notes

There are mentions of potential confusion regarding the direction of arrows in the original sketch and the implications of starting multiple threads for the same problem. Participants are also considering the limitations of the reflections and the visibility of patterns within the setup.

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?

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.
Does somebody have a good way to describe it?
"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.
