Beneath the original 1912 office building of the Carnegie Observatories on Santa Barbara Street in Pasadena sits a ...

Today, astronomers seek to observe the faintest and most distant objects possible. Extremely Large Telescopes (ELTs), with apertures in the order of several dozen meters, are the next generation ...

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 ...

Diffraction gratings separate different wavelengths of light using a periodic pattern embedded in the grating. The diffraction pattern can affect the amplitude and/or phase of the incident light as ...

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 here we are with [Twisted & Tinned], who’s made a novel clock with a ...

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 ...
