SUMMARY

The discussion centers on the optical phenomenon of light reflection between two parallel mirrors. When two mirrors face each other, they reflect images of each other indefinitely, producing smaller and smaller reflections until the resolution limit of the mirrors is reached. The presence of photons plays a crucial role, as they bounce back and forth between the mirrors, creating a series of diminishing images. The introduction of an observer and a light source would further complicate the reflections, adding layers to the analysis of light behavior in this scenario.

PREREQUISITES
  • Understanding of basic optics principles
  • Familiarity with the behavior of light and photons
  • Knowledge of mirror properties and image formation

  • Explore the concept of infinite regress in optical systems
  • Study the effects of distance on image resolution in mirrors
  • Investigate the role of observers in optical phenomena
USEFUL FOR

Students of physics, optical engineers, and anyone interested in the principles of light behavior and reflection in mirror systems.

If two planes of mirrors (infinite in all directions) were facing each other with nothing in between what would they reflect? How does light come into play in this?
If they were not directly stuck to each other (in which case there would be absolute black, no light I assume) but at a distance apart?

Just my thoughts, not an expert answer.
I suspect that they would each reflect a slightly smaller version of the opponent... indefinitely. The end point, I believe, would be when the resolution of the image exceeds the resolution of the mirror.
 
The only sensible answer I've got is "any photons already there would bounce back and forth between the mirrors". There would be more to say if an observer and light source were included.
