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 ...

Adam Sherwinski teaches ciLiving host, Jaclyn Friedlander about light refraction. Watch how light bends when it passes through water in this fun and easy science experiment! In this video, we explore ...

Waves close wavesVibrations that transfer energy from place to place without the transference of matter. - including sound and light - can be reflected at the boundary between two different materials.

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 ...
