A diffraction grating splits a beam of light up into multiple beams whose position is determined by both the wavelength of the light and the properties of the grating.

Scientists have observed “bending” atoms using a crystal grating—an experiment once believed impossible at the high energies required. The authors of a new, non-peer reviewed study detail ...

The Grating Challenge 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), ...

A preprint describing the experiment is available via arXiv and is yet to be peer-reviewed. [H/T: New Scientist] White light passing through a diffraction grating creates this pattern.

Recently, physicists from The Massachusetts Institute of Technology conducted a new experiment with slits through which light was transmitted with incredible atomic precision. The results of their ...

Q: What are diffraction gratings? A diffraction grating is an optical component for spectroscopy that splits light into different wavelengths. A typical diffraction grating has thousands of ...

Essentially, they form a diffraction grating, except photonic crystals only produce certain colors, or wavelengths, of light, while a diffraction grating will produce the entire spectrum, much ...
