When it comes to light, certain types of fabricated materials behave in a radically different manner from ordinary materials like water and glass: they have negative refractive indices, so that light ...

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 ...

GRAND RAPIDS — Every day we see and use light for numerous daily functions, but did you know you can actually bend light? Its called refraction and our experiment today is going to show you how its ...
