Why can't a broken mirror shine on people?
Law of light reflection: reflected light is in the same plane as incident light and normal line; Reflected light and incident light are separated on both sides of the normal; The reflection angle is equal to the incident angle.
The imaging principle is as follows:
When people look in the mirror, the light emitted by people reflects back on the mirror and into people's eyes, so that people can see themselves.
Because light doesn't shine into people's eyes from the image in the mirror, only because people's brains can't receive the reflection information of light can they intuitively "see" a person appearing in the mirror, and there is no other person in the mirror who emits light and enters the eyes of outsiders, so people see a virtual image. In subordinate physics, the intersection set of the opposite extension lines of the actual light is called the "virtual image" of the object.
