When two or more light waves interact with one another, they result in the formation of different interference patterns. British physicist Thomas Young first demonstrated and explained these patterns ...

Even diffuse objects like clouds or sugar cubes cast shadows, because they’re disordered media that scatter light waves. But now, researchers at TU Wien and Utrecht University have found a way to ...

Physicists have trapped light inside a miniature ring so that it needs two round trips to get back to its initial configuration, like an ant that must make two circuits around the surface of a Möbius ...
