What Do You Think?

You can see yourself in a mirror by observing light reflected from you that the mirror reflects back into your eyes. The mirror creates a virtual image of you the same distance behind the mirror that you are in front of it. But you can see only that part of your body that faces the mirror, since light from the back of your head moves off in another direction and does not hit the mirror. To see the back of your head requires a second mirror, which is why hair stylists hold up a second mirror to show their clients their new haircut. If you covered the walls of a room with mirrors, you could see many different reflections of the back of your head.
