Diffraction gratings are periodic optical structures that disperse incident light into constituent wavelengths by interference. They form a cornerstone of modern optical instrumentation, underpinning ...

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 ...

Measurement setup: The laser (a) emits coherent light, which passes through an aperture stop and the grating under test (b). The intensity of the diffraction orders is measured using a movable ...
