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 ...

FORT WAYNE, Ind. (WANE) A gloomy day can’t keep science away! Science Central’s Martin Fischer joins NewsChannel 15 to demonstrate experiments focused on light. Fisher showed two simple experiments ...

The alternative text for this image may have been generated using AI. In this Letter, we experimentally demonstrate nonlinear optical negative refraction in thin metallic nanostructures. We use a ...

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.

There are different ways to investigate refraction in rectangular blocks. In this required practical activity, it is important to: make, measure and record the angles of incidence accurately using a ...
