Spectral analysis. 19th-century illustration of an experiment performing spectral analysis of light from a carbon arc light (far left) and bunsen burners with sodium flames (centre left). The resulting light is passed through lenses, split with a prism, and the resulting spectrum displayed on a screen (far right). The spectrum contains bands corresponding to the presence of carbon and sodium. This illustration is from 'Physique Populaire' (Emile Desbeaux, 1891).
