Light guide light

Specifications: 700 × 700 × 1000; light travels in a straight line in the same medium. But in fiber, light can travel along the curve. This is due to the fact that light forms a total reflection at the interface between the core of the fiber and the sheath. After countless total reflections, light passes through the curved fiber. The condition of total reflection is that light is emitted from the light-tight substance to the light-dissipating substance; the incident angle is greater than the critical angle. Here, the plexiglass is a light-tight substance; the air is a light-staining substance.
