A flipped image or reversed image, the more formal term, is a static or moving image that is generated by a mirror-reversal of an original across a horizontal axis (a flopped image is mirrored across the vertical axis).

Why do mirrors flip you?

The image of everything in front of the mirror is reflected backward, retracing the path it traveled to get there. Nothing is switching left to right or up-down. Instead, it’s being inverted front to back. … That reflection represents the photons of light, bouncing back in the same direction from which they came.

Do Mirrors flip your face?

Mirrors don’t reverse left and right either – that’s just our interpretation of what happens. Your reflection in the mirror is actually reversed front to back – if you have a mole on left side of your face, it still appears on the left side of the reflection.
