Scientists have demonstrated that negative refraction can be achieved using atomic arrays -- without the need for artificially manufactured metamaterials. Scientists have long sought to control light ...

A rainbow reveals with colors what otherwise remains hidden: light is "refracted" by transparent matter, in this case water ...

Refraction—the bending of light as it passes through different media—has long been constrained by physical laws that prevent independent control over how light waves along different directions bend.

Alpha Centauri sits more than four light-years away, close enough to fascinate generations of dreamers and far enough to make ...

In this activity, pupils will learn about refraction and reflection, and how they’re different. You only need simple bits of ...
