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 ...

When we taught a class of first year chem/biochem majors about spectroscopy, we introduced them to it with a task. It was to dig through bins full of the things shown below (many of them 3D-printed ...

THE L III absorption edges of aluminium and magnesium have been measured. Since the continuous X-ray spectrum in this region (above 100 A.) is very feeble, I have used optical spark spectra from ...
