1, when you look in the mirror, you can see another "you" in the mirror, and the "person" in the mirror is your "image". In the mirror image, your left hand is still on the left and your right hand is still on the right, but if two people face each other, your left hand is on the other's right and your right hand is on the other's left. This effect is also called mirroring.

This is a physical phenomenon. It means that the light of the sun or lamp shines on people and is reflected on the mirror. The flat mirror reflects the light into people's eyes, so we see our virtual image in the flat mirror.

2. Features

But in experiments, we often use glass plates instead of flat mirrors. Because the flat mirror is replaced by the glass plate, although the image is not as clear as the flat mirror, the image of candle A can be observed at the same time, which skillfully solves the problem of determining the position and size of the image. In order to see the image in the mirror more clearly, we require the object in front of the glass to be as bright as possible, while the environment is as dark as possible. The object behind the glass should be as bright as possible and the environment should be as dark as possible. Therefore, the plane mirror imaging experiment is suitable for dark environment.

The plane mirror can change the propagation path of light, but it cannot change the beam properties, that is, when the incident light is a parallel beam and a divergent beam, it will still be a parallel beam and a divergent beam after reflection.
