or at 2,200° K is also given. This allows us to note how powerful is the absorption of H20 and C02 in the bands even when so short a path as 11.5 meters is traversed by the beam. In other parts of the spectrum, free from great absorption bands, it will be seen that the computed curve is a very… … Fig. 37. — Energy curves of Nernst lamp radiation. Figure 38 shows the percentage of absorption found at all wave lengths from 1.2m to 9.0m, with different quantities of water vapor and carbon dioxide in the path. A curve (the fine dots) from the work of Paschen is included. Other data of his are…
