The spectrometer analyzes light from a laser with a wavelength l = 6328 A, scattered at an angle j = 90° in water (n = 1.5). What should the resolution of the spectrometer be in order to distinguish lines corresponding to inelastic light scattering with the creation or absorption of a phonon? The speed of sound in water is s = 1.5•103 m/s.
