How the mirror reflects people.

The law of reflection of light: the reflected ray is on the same plane as the incident ray and the normal; The reflected and incident rays are located on either side of the normal; The angle of reflection is equal to the angle of incidence. It can be summarized as: "three lines are coplanar, two lines are separated, and the two angles are equal".

The image in a plane mirror is formed by the intersection of the extension lines of the reflected rays of light, so the image in a plane mirror is a virtual image. The virtual image is equal to the size of the object and the distance is equal. The image is equal in size to the object. So the image and the object are symmetrical to the mirror.

According to the characteristics of plane mirror imaging, the size of the image and the object are always equal. No matter how the distance of the object from the plane mirror changes, the size of the image it forms in the plane mirror always remains the same, and it is always the same size as the object. However, due to the fact that people have the feeling of "near big and far small" when observing objects, when people walk towards the plane mirror, the vision does feel like it is "getting bigger", which is because the size of the object observed by the human eye is not only related to the real size of the object, but also closely related to the "viewing angle".

A straight line is drawn from the human eye to each end of the object being observed, and the angle between these two straight lines is the "viewing angle". When a person approaches the plane mirror, the distance between the image and the person is smaller, and the angle of view of the object is increased, so the image seen becomes larger, but in fact, the image and the size of the person are always equal, which is the reason why the human eye sees the object "near and far away". This is just like when you see a person walking towards you in the distance in front of you, at first you see a small black shadow, slowly getting bigger and bigger, and when you walk in front of you, it is even bigger, in fact, that small black shadow is the same size as the person who walks in front of you, just because of the visual relationship, the image of the plane mirror and the object are symmetrical with respect to the mirror surface, so the person gradually gets closer to the mirror.

The image must also gradually get closer to the mirror, and the human feeling is "near big and far small", which is a visual effect.

The environment we are in is not a single ray of light, but composed of different rays of light, that is to say, there is not only one light incident, different lights incident in different directions, will be reflected to the human eye at different angles, will have an impact on each side of the fragment.

The paddy field is a mirror that reflects (the grass), reflects (the trees), reflects (the rainbow), and reflects (the sky).

Farmers are planting seedlings, planting (in the sky), planting (on the rainbow), planting (on the big trees), planting (in the grass).

Mirror people are very rare, and their bodies are the opposite of ordinary people. However, the physiological function of a mirror person is no different from that of a normal person. That is, it has no effect on you, and you can live like an ordinary person.

There is a corpse of a mirror man in our school, which is placed in the exhibition hall as a treasure (abdomen dissected). When I saw it, I did think that the corpse was very precious.

If you are really a mirror person, if the doctor does not find out when receiving medical care, it is better to mention that you are a mirror person, because mirror people are indeed very rare and can lead to misdiagnosis, especially when it comes to stomach problems. When you see Chinese medicine, you should also say it, because the pulse of the left and right hands has different meanings.

Oh, by the way, if I were a mirror person, I would leave a will and donate my body to a medical school when I am old.
