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?

Answer Posted / tase
when the person lift the right hand the mirror also lift the
REFLECTION of the right hand, when the person lift the left
hand the reflection will also lift the REFLECTION of the
left hand, and finally when the person list his head the
mirror also lift the REFLECTION of the head. The reflection
in the mirror is by no means identical with the person , the
one someone see in the mirror is not the same thing that
someone that will sit instead of the mirror will see you.
So the mirror just "appears" to reverse left and right but
actually the "mirror"'s left is not identical with our left so.
Or we can think like this: Since the problem said that our
left means the mirror's right then using the same approach
means that our UP is the mirror's DOWN, so wen we lift the
head UP the mirror image will lift the head DOWN.
