Is having one side that exactly mirrors the other?

The image of an object as seen in a mirror is its mirror reflection or mirror image. In such an image, the right side of the object appears on the left side and vice versa. Any object that has a bilateral symmetry will have its mirror image the same as that of the object.

Is the mirror what I look like to others?

A mirror does not show what you look like in real life. When you look at the mirror, you do not see the person that other people see. This is because your reflection in the mirror is reversed by your brain. When you raise your left hand, your reflection will raise its right hand.

Why do mirrors reflect left to right but not up and down?

Mirrors do not flip left to right. They flip front to back. Mirrors reflect light rays such that the angle of reflection equals the angle of incidence.

Why do mirrors reflect two images at the same time?

Most mirrors are made with the metallization on the back side, so that it can be protected by another layer of stuff. This gives a double reflection, since the air-glass interface on the front side of the glass reflects about 4\% of the incoming light. When viewed at an angle, the two images appear offset from one another.

What is the horizontal reversal of the mirror?

Raise your North hand. The image raises its North hand. Raise your South hand… The mirror has no horizontal reversal. It is a peculiarity of English that we use global axes to describe large objects, like countries, but local axes for small objects like those in a room.

Why does the mirror flip left and right?

The mirror doesn’t flip left and right; it flips forward and back. Your front is farther north than your back, but your reflection’s front is farther south than its back. Your feet and the reflection’s feet both face down. The wrist with the watch is on the west side, both for you and your reflection.
