Why do mirrors reverse left and right but not up and down?
In: Physics
They don’t.
The way you think about it is that if you want to get to that position, you’d turn around – essentially walking around an imaginary vertical pole. But why a vertical pole? Why not a horizontal pole? If you flipped over instead, you’d be doing a handstand. You’d be the opposite way up from the image, but left and right would be the same.
