If you studied advanced physics at high school, there's a good chance that you remember Snell's law, which states how a ray of light bends when it crosses a boundary between two media. According to ...

Horiba has developed a particle size distribution measuring device that accurately measures particle size distribution even in the presence of similar-shaped particles. The device uses image ...

Our industrialized society releases many and various pollutants into the world. Combustion in particular produces aerosol mass including black carbon. Although this only accounts for a few percent of ...

The familiar claim, “Nothing can go faster than light,” is, in fact, misleading. Light travels at different speeds in different media. The speed depends on the medium’s index of refraction (n). Light ...
