The previous answer was wrong to claim materials are transparent or reflective depending on whether they have a crystalline structure. Mercury is liquid, not crystalline, and is reflective. Diamond is ...

A new kind of mirror is emerging from quantum physics labs, one that exists not as a chunk of polished glass but as a ...

Engineers have found a way to make liquid metals switch between reflective surfaces or those that scatter light. The transition only requires a small zap of electricity and could be used to make ...

Infinite mirrors are a fun party trick, but the physics behind this phenomenon explains why it may not be true. When you purchase through links on our site, we may earn an affiliate commission. Here’s ...

Scientists have demonstrated, for the first time, a new type of mirror that forgoes a familiar shiny metallic surface and instead reflects infrared light by using an unusual magnetic property of a non ...

Introduction Can you imagine a bouncy ball that could bounce back and forth between two walls, infinitely—that is, forever? Wouldn't that be amazing? What if, instead of a ball, light was bouncing ...

Mirrors such as those found in a bathroom tend to be made from a sheet of transparent glass or plastic and a layer of smooth, polished aluminium (or in older mirrors, silver). The reason why light ...
