Up to 75% of light reflects from just 2000 atoms aligned along an optical fiber, an arrangement that could be useful in photonic circuits. Atomic mirror. Red light sent through an optical fiber is ...

At night, are you opening your science workbook and staring at the drawing problems for "light reflection and ...

Ever wonder how a mirror works? If you want to find the path that light takes when reflecting off a surface, you could use Fermat's Principle. This states something like this: The path that light ...

A team of researchers from Rensselaer Polytechnic Institute has created the world’s first material that reflects virtually no light. Reporting in the March issue of Nature Photonics, they describe an ...

Light propagation is usually reciprocal, meaning that the trajectory of light travelling in one direction is identical to that of light travelling in the opposite direction. Breaking reciprocity can ...

Mirrors such as those found in a bathroom tend to be made from a sheet of transparent glass or plastic and a layer of smooth, polished aluminium (or in older mirrors, silver). The reason why light ...
