By extending these straight lines a graphical picture of spectral luminosity of the dye-solution is obtained for any concentration of depth. It is seen that this solution in great depth… … CavC£AITR^T/OA/ OFI D£pr» Fig. 140. — Rosazeine. after the absorption-band of a weak solution or small depth is passed. Incidentally, it will be noted that the slope of line 0,44/x is less than that of 0.58m which shows that in low concentrations or in relatively small depths of a higher…
