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.
