Why Do Mirrors Flip Left & Right (but not up & down)?

The video explores how mirrors create the illusion of flipping images. It explains that mirrors do not flip left-right or up-down but rather invert depth, making objects appear reversed in and out. This is due to the principle of specular reflection, where light reflects at equal angles. The video uses the analogy of a parallel universe to describe this phenomenon. It also clarifies that words appear flipped in mirrors because we physically turn them, not because of the mirror itself. Finally, it discusses how multiple mirrors can create different flipping effects.
