This page contains hints, solutions, and advanced challenges for our diffraction grating challenge. If you would like a grating (or a set for your class if you are a teacher), please contact us at ...

A U.K.-Portuguese research group is proposing a new solar cell design based on diffraction gratings – optical components that split and diffract light into several beams. They claim this could lead to ...

Zoe Kleinmann and a student make a pattern of light with translucent cups. Zoe Kleinmann and a student explore patterns. First they create units of two connected plastic cubes to create an AB pattern.

As we all know, light on its own tends to travel in a straight line. When it gets sent through an aperture like a flashlight, diffraction occurs, which causes the beam to widen and lose its intensity.

THE attention given, in this laboratory and elsewhere, to the effects produced by passing a beam of Röntgen radiation through crystals suggested to me that it might be of interest to examine the image ...

Researchers built a silver-grooved chip that channels laser energy into nanometer-spaced peaks, beating the diffraction limit and aiding light-matter studies.

(Nanowerk News) Until recently, it was widely believed among physicists that it was impossible to compress light below the so-called diffraction limit (see fact box), except when using metal ...
