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 ...

One of the coolest things about physics is that the same basic concept can pop up in several seemingly unrelated things: say, a CD, the seed shrimp’s antennae, certain fossils in the Burgess shale, ...

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 ...

Diffraction gratings are beautiful things, bending transmitted and reflected light and splitting it into its component wavelengths to create attractive iridescent rainbow patterns. It’s the same ...

A variety of ultrathin nanomechanical diffraction gratings that have been fashioned from the “wonder material” graphene have been created by an international team of researchers. The team wanted to ...
