How do the patterns in a kaleidoscope come about? It turns out that they are created by the reflection of glass mirrors. It is composed of three sides of glass mirrors to form a 'tetrahedron'.prismPlace some colored glass fragments on one side, and after they are reflected by three mirrors, they will form symmetrical patterns, resembling blossoming flowers. The principle of a kaleidoscope lies in the reflection of light, and a mirror uses the reflection of light to achieve this.ImagingThe principle of this imaging technology was developed in China.prehistoricThe ancients of the time had already mastered it. Ancient books such as ZhuangziIn the text, there is a saying of 'Identifying with Water,' which means using still water as a mirror. It is said that the true Kaleidoscope toy was invented by British physicist David Brewster in 1816.
