Invisible orbit

The reason why glass tracks can achieve invisibility in liquids is because they have the same refractive index as the surrounding liquid. The refractive index is defined as the ratio of the propagation speed of light in a vacuum to its propagation speed in a specific medium. At present, people are researching how to achieve invisibility by matching the refractive index of materials and the environment, and then designing stealth materials.

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

(1) The principle of orbital invisibility is that when glass is in the air, the propagation speed of light in the glass will exceed that of the glass, causing the light to bend. The propagation speed of light is very close in vegetable oil mixed liquids and glass. This also caused the glass to seem to disappear into the vegetable oil mixture. (2) The propagation speed and refractive index of light vary in different media due to the refractive index of the medium. The refractive index (n) is a physical quantity that describes the ratio of the speed of light propagation in a medium to its speed in vacuum. The speed of light propagation in vacuum is the fastest, approximately 299792458 meters per second (m/s), which is the standard value for the speed of light (c). The formula for refractive index can be expressed as: n=c/v, where c is the velocity of light in vacuum and v is the velocity of light in a specific medium. For visible light, the refractive index of water is approximately 1.33, while for glass.
