"WebDiffraction gratings are used to study the spectrum of light from different elements. When an atom gets extra energy (is excited from its ground state), it releases energy in the form of an electromagnetic wave. The wavelength of the light released depends on the energy levels inside the atom. " - Design of diffraction gratings chapter 5
