imaging with a flat mirror; Change the light path; Expand the vision space, etc. Flat mirrors are widely used in life, for example, the dressing mirror used at home, the mirror around the wall in the practice room, and the small mirror put in the mouth when the dentist examines his teeth are all flat mirrors; There are flat mirrors in periscope, microscope, projector, etc. used in submarines.
Imaging characteristics of the plane mirror:
The plane mirror presents an isometric virtual image; The distance from the image and the object to the mirror is equal; The connecting line between the image and the object is perpendicular to the mirror; Images and objects are symmetrical about mirrors.

Characteristics of flat mirror imaging:
But in experiments, we often use thin glass plates instead of flat mirrors. Because the glass plate is used instead of the flat mirror, although the image is not as clear as the flat mirror, the image of candle A can be observed at the same time, and the problem of determining the position and size of the image can be skillfully solved.
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, and the environment to be as dark as possible. The object behind the glass does not need to be lit, 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 route of light, but it can't change the beam properties, that is, when the incident light is a parallel beam or a divergent beam, it is still a parallel beam and a divergent beam after reflection.
