Why do mirrors flip left and right?
Show answer & explanation
Answer: They flip front and back actually
Brain processes images backward — Wrong. Brain processes correctly. Confusion comes from mental rotation—we imagine facing the mirror, which swaps left/right in our mind.
Reflection inverts everything — Wrong. Mirrors don't flip left/right or up/down—they flip front/back! Your nose stays in middle, feet stay down. Confusion is perceptual.
They flip front and back actually ✓ — Correct! Mirrors flip front and back (depth inversion), not left and right! Raise right hand—reflection raises hand on same side (your right). Confusion arises because we imagine rotating 180° to face our reflection, which WOULD swap left/right. Mirror reverses perpendicular axis (toward mirror ↔ away). Writing looks backward because front/back of letters flip. Up/down unchanged. Mind-bending perceptual illusion!
