In this activity, pupils will learn about refraction and reflection, and how they’re different. You only need simple bits of ...

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 ...

This video explains why a wave changes direction when it passes from one medium to another, in a process called refraction. The change in direction of a refracted wave can be drawn using a ray diagram ...
