Parallel Mirrors

Floor 1 | Mirrors in Mind
Looking between the pair of parallel mirrors, you see repeating images stretching off to left and right. With perfect reflectance they’d continue for ever. Put the soft toy between the mirrors: you’ll see it alternately head-tail-head-tail as it’s reflected alternately from front and back. Experiment with the light stick: how many reflections from the light to the first green image? And to the first red image? Try tilting one mirror: the little points of light trace out the arc of a huge circle. Consider: if the mirrors were perfectly parallel, that circle would be infinitely large!
