INTERFERENCE METHODS IN SPECTROSCOPY 343 {b) Cadmium red and mercury green rays, A = 6438 andX = 5461. p = 0042, therefore e^ -r «a = - s-iju/^.

By means of three standards Fabry and Perot measuredthe wave-lengths of fourteen lines in the arc spectrum ofiron, and thirty-three in the solar spectrum. In both seriesof…
