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 ...

In this activity, pupils will learn about refraction and reflection, and how they’re different. You only need simple bits of ...

FORT WAYNE, Ind. (WANE) A gloomy day can’t keep science away! Science Central’s Martin Fischer joins NewsChannel 15 to demonstrate experiments focused on light. Fisher showed two simple experiments ...

A rainbow reveals with colors what otherwise remains hidden: light is "refracted" by transparent matter, in this case water ...

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 ...

THE experiments of Hill and Swallow 1 in August 1949 showed that the method of seismic refraction shooting at sea, which had been developed at Cambridge, was suitable for deep ocean work. Effort was ...

Physicists are involved in an unusually heated debate over the reality of a new kind of refraction and about the possibility of making perfect lenses. Edwin Cartlidge reports. If you think science is ...
