For the first time, scientists have demonstrated that negative refraction can be achieved using atomic arrays - without the need for artificially manufactured metamaterials. Scientists have long ...

Adam Sherwinski teaches ciLiving host, Jaclyn Friedlander about light refraction. Watch how light bends when it passes through water in this fun and easy science experiment! In this video, we explore ...

When light passes through materials, it typically changes direction and bends in predictable ways. This change in direction, known as refraction, is caused by a change in the speed of light as it ...

Guy Bartal, from the light refraction lab at Berkeley, talks with Scott Simon about the research they're doing on "invisible cloaks." Bartal overseas research in this lab, and is a co-author of two ...

What color is the coronavirus? Conventional optical microscopes are unable to generate high-resolution, colored images of viruses and bacteria. Expensive equipment is used to view them in a more real ...

IN preparing an elementary lecture on Light, intended to be given at the Taunton College School, I have had to consider how best to explain the somewhat abstruse principle of optical refraction. It is ...
