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 ...

The diffraction grating of a spectrometer partially determines the optical resolution that can be achieved by the spectrometer and also determines the wavelength range. Selecting the correct grating ...

We’ve seen just about every possible way to make a clock here at Hackaday over the years. So it’s rare to have a first, but ...

First experimental observation of matter-wave diffraction in a short-lived electron-positron atom using a graphene-based diffraction grating. (Nanowerk News) One of the discoveries that fundamentally ...

THE June issue of the Journal of the Franklin Institute contains two interesting letters from the second volume of the Transactions of the American Philosophical Society (1786), from which it would ...
