Imagine shining a flashlight into a material and watching the light bend backward—or in an entirely unexpected direction—as ...

A team of scientists led by Academician Professor Xiang Zhang, President and Vice-Chancellor of The University of Hong Kong ...

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. Denmark facing "decisive moment" over ...

Light bends when travelling through a concentration gradient of sugar in water. The top layer of liquid is pure water while the bottom layer is concentrated sugar water. In these layers, there is no ...
