Sunlight is made up of multiple different wavelengths of light, each of which is affected slightly differently as it passes ...

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 ...

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 video, I demonstrate a fun science trick using a simple arrow, a glass, and water. Watch how the arrow magically ...

Physicists in Germany claim to have found the first naturally occurring material that has a negative, rather than a positive, refractive index. The material -- a metallic ferromagnet -- is very ...

To demonstrate a quick way of calculating the optical difference between two refractions using vector analysis, and to express this as a score for examination purposes. An existing formula is applied, ...

WHEN a concentration gradient in a vertical column of solution, for example, an ultracentrifuge cell, is investigated by a refraction method, it is desirable to obtain a diagram relating the ...
