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 ...

I test a series of light experiments to explore reflection, refraction, and optical illusions, demonstrating how light behaves in surprising and educational ways. Trump removes nearly 30 career ...
