Light is reversible (reversibility). That is: Light can be irradiated from point A to point B, from B bursts to point a. Why is there one-way glass? The secret is that the glass surface is coated with a thin silver film or aluminum film. Such a glass is not reflective of all the incident light, but can let the incident light pass through. And one-way glass can be seen unilaterally, Pangyi strength. Invisible side brighter, visible side darker. The invisible side of the strong light is mostly reflected by the silver film, but the weak light from the visible side is not visible because of the strong reflection of light, even invisible. So, from the bright side, it looks like ordinaryMirrorThe same. On the other hand, as the light shines through the thin silver film from the bright side, the faint reflected light emitted by itself is invisible. As a result, unidirectional glass is still reversible with light, only one-way visible.
