In 1 you use a photometer to measure the intensity of the light which is given out by a substance or intensity of light emitted by it. Measurement involves wave lengths ,energies etc. In 2 is included all methods of producing and analysing light spectra usingspectroscopes, spectrographs,spectrometersand spectrophotometers.
