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.

Researchers are making progress toward a “perfect lens” that will be able to resolve an organelle assembling a protein or a virus attacking a cell. From ribosomes assembling proteins to viruses ...

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 ...

Geometric optics explains how light behaves when it reflects, refracts, and forms images through lenses and mirrors. From total internal reflection in fiber optics to the sparkle of rainbows, these ...

Nearly a decade after getting waves of light to bend backward, physicists have done the same with electrons. Electrons coursing through a sheet of carbon atoms exhibited negative refraction, bending ...

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

Please provide your email address to receive an email when new articles are posted on . The Light Adjustable Lens performs well in post-RK eyes, with good results that remain relatively stable over ...

A new laser under development by BAE Systems could boost a high-flying airplane's ability to spot targets on the ground, creating a temporary floating "lens" in midair that magnifies objects. The same ...
