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 ...

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 ...

The film explores the dual nature of light, demonstrating its behavior as both a wave and a particle through an experiment involving a double slit. It shows how light creates an interference pattern, ...

It’s in your physics textbook, go look. It says that you can either model light as an electromagnetic wave OR you can model light a stream of photons. You can’t use both models at the same time. It’s ...

Light is well known to exhibit both wave-like and particle-like properties, as imaged here in this 2015 photograph. What's less well appreciated is that matter particles also exhibit those wave-like ...

When a beam of energetic electrons travels through a plasma, the space charge at the tip of the beam knocks electrons from the ions in the plasma, leaving the ions with a larger positive charge. If ...
