Exploiting a novel technique called phase discontinuity, researchers have induced light rays to behave in a way that defies the centuries-old laws of reflection and refraction. The discovery has led ...

When people look into a mirror, they see an image of themselves behind the glass. That image results from light rays encountering the shiny surface and bouncing back, or reflecting, providing a ...

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 ...

PITTSBURGH (KDKA) -- Without light, we can't have sight. We see objects because of how light interacts with those objects, our eyes pick up that light, and our brains interpret it. This seems rather ...

Light energy travels in straight lines and in waves. Light energy travels in straight lines and in waves. When light strikes a plane or a flat surface, it reflects in a manner that is predictable. For ...

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 ...

Ever wonder how a mirror works? If you want to find the path that light takes when reflecting off a surface, you could use Fermat's Principle. This states something like this: The path that light ...

Created more than 400 years ago, the telescope is a tool that has allowed both amateurs and scientists alike to explore the sky in much more detail than they ever could with their naked eyes. All ...

In my previous Photography Snapshot, I discussed the importance of light and how it bounces to create images. We discovered that the most primitive form of photography was the camera obscura, which ...
