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 ...

Laboratory of Behavioral Ecology and Evolution at Seoul National University Light and foraging ants seem totally unrelated, but they have one thing in common: they travel along time-reducing paths.

WXMI — In our science experiment today, we look at a disappearing coin trick, which really is no trick at all. It illustrates density and refraction. Some things are more dense (or heavier) than other ...

Ray Optics often overwhelms Class 12 students due to formulas and sign conventions. An expert board examiner explains why ...
