This is mainly because of the refraction principle of light, the thickness of this mirror is different, and with the unique pattern on the mirror, it is difficult to see that its thickness is different. According to the mirror, the thick part has a large curvature and the thin part has a small curvature, but it is difficult to find if you look at it at ordinary times, so it has a very mysterious feeling and a projection effect.

In ancient mythology, there is a saying that looking at a magic mirror. When people talk about looking at a magic mirror, they aim the mirror at the monster, and then the monster will show its true colors. The reason why this kind of mirror has a magic mirror is that it will project what it shines, thus projecting this silver image to other places, so there is a magic mirror. However, this mirror is not very mysterious. It's just that in the middle and late Western Han Dynasty, some mirror craftsmen had a whim and created something even more fantastic to fool concubines.

If this kind of mirror passport uses physics, through the combination of optics and mechanics, through the reflection of natural light, the mirror projects the image onto the wall. However, I was also amazed at the creativity of the ancients. It is difficult to make such a mirror in modern times. But unfortunately, the production process of this kind of mirror has long been lost. Moreover, due to the lost craftsmanship, there are so few things circulating in the world, and perhaps even less can be seen by the world because of personal collection.

Despite the advanced technology, many mysteries have been slowly solved, including this so-called magic mirror. In fact, this mirror only uses physical optics. Of course, there may not be such an idea in ancient times. Only through constant thinking and discussion can such an achievement be achieved.
