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 ...

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 ...

In the year 1900, no one would have guessed that light — to all appearances an ethereal wave-like phenomenon — might take the form of localized particles. Nor would anyone have expected that the ...
