ELI5. Why do mirrors flip the image horizontally and not vertically?
In: Physics
Mirror flip images back to from not horizontaly
Put a mirror north of you and look directly at it. Your right arm is on the east side and if you move it the reflection of you moves the eastern arm. The same is for your arm to the west. Jump up and down and the reflection moves the same way.
There is a difference if you talk about left and right arm but that is because it is a relative definition and it no different to if you look at someone saying in front of you looking toward you
But if you move away from the mirror to the south the reflected image move to the north. This is the flip back to front.
Mirrored text looks like that because you look at it from the back. If you write text on a window and look at it from the backside look just like in a mirror. You can use a mirror to read that text correctly.
