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 ...

Students use mirror equations to determine the position and type. Students use mirror equations to determine the position, type, and size of mirror images for curved mirrors mathematically. Optical ...

A new method predicts leaf optical properties from traits, improving canopy light modeling and photosynthesis estimates in ...

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

We are surrounded by waves. tiny vibrational waves transport sound to our ears. Light waves stimulate the retinas of our eyes. Electromagnetic waves bring radio, television and endless streaming ...

Can we turn back time? Ask a savvy physicist, and the answer will be “it depends.” Schemes for retrograde time travel abound but usually involve irreconcilable paradoxes and rely on outlandish ...
