Spectral study of Na source with a smartphone and a diffraction grating

A home-made spectrometer, based on the use of inexpensive diffraction transmission gratings coupled with a smartphone camera, can be assembled and employed to obtain quantitative spectra of different sources with surprisingly high accuracy to the point of being able to observe the separation of the...
