Will parallel mirrors create an infinite number of reflections?
No. Not a single mirror reflects 100% of the light, part of the light energy is necessarily absorbed, so that each subsequent reflection is dimmer and after a certain number of iterations of light is simply not enough to draw a distinguishable picture. In addition, to form each subsequent reflection, light travels more and more, and the picture becomes smaller. Imagine that we have a perfect mirror. Decreasing, one day the reflection will become less than the resolution of the eye. And we will not see him. You can, of course, use a telescope, but when the reflection size approaches the boundary of the light wavelength, no optics will help us.
