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 ...

A laser pointer shining on a diffraction grating or CD creates a series of diffraction spots depending on the spacing of the lines or pits in the grating or CD and the wavelength emitted by the laser.

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 ...
