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 ...

Recent experiments that demonstrate the negative refraction of light could bring a heated scientific debate to a close, and give negative-index materials a positive future Figure 1: Negative-index ...

The origin of a rainbow can be answered by almost everyone. We learn the physics behind a rainbow very early in our lives, but the phenomenon responsible for it does not linger in the minds of ...

An unusual optical phenomenon explains why the Titanic struck an iceberg and received no assistance from a nearby ship, according to new research by British historian Tim Maltin. Atmospheric ...

There are many glorious science-based terms when it comes to surfing. We all talk about swells, of course, the underwater energy that creates a breaking wave. But we'll look at swell angles and ...

To demonstrate a quick way of calculating the optical difference between two refractions using vector analysis, and to express this as a score for examination purposes. An existing formula is applied, ...
