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 ...

A material that is capable of the “reverse diffraction” of light and that is inspired by butterfly wings has been made by researchers in the US. The structure combines features of the butterfly’s ...

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 ...
