Why is that a party in a mirror are reversed, but not up or down?
I'm trying to think, but can not reach a conclusion.
It actually does not invest. Back is a picture of what is directly in front of it. His right eye is on the right side of the image you see. If actually reverses, he had seen his right eye in the left side of the image you see (like when people are in front of you, his right eye is on the side left of what you see).
