Refraction—the bending of light as it passes through different media—has long been constrained by physical laws that prevent ...

This is refraction, and the way a wave breaks can also be impacted by what's going on under the surface on the ocean floor. So every surf spot in the world has its own unique footprint.

Negative refraction, however, is a counterintuitive effect where light in a medium bends in the opposite direction to what is typically observed in nature, challenging conventional understanding ...

We present experimental scattering data at microwave frequencies on a structured metamaterial that exhibits a frequency band where the effective index of refraction (n) is negative. The material ...

Wrong way: electrons undergoing negative refraction at a p–n junction. (Courtesy: Cory Dean) The negative refraction of electrons in graphene has been seen for the first time in experiments done by ...

But only Newton saw what this implies: that refraction is then all there is to it. The colors themselves are already in the white light, and all the prism does is to separate them out.
