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 ...

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 ...

A rainbow reveals with colors what otherwise remains hidden: light is "refracted" by transparent matter, in this case water droplets. This same physical effect underlies many everyday technologies, ...
