Imagine you are standing in front of a mirror, facing it.
Raise your left hand. Raise your right hand. Look at your
reflection. When you raise your left hand your reflection
raises what appears to be his right hand. But when you tilt
your head up, your reflection does too, and does not appear
to tilt his/her head down. Why is it that the mirror appears
to reverse left and right, but not up and down?

if you place the mirror on the floor it will appear to reverse up down as well. Look at a reflective pond for an illustration of this point. The light rays that reach the eye from the mirror have taken the shortest path from the image to the mirror, a mirror, unlike a pin-hole camera, reflects the light rays.
