e being about iioo°C. Using these twowave lengths the Xmax, for this energy input, can be calculatedfrom the equation given by Paschen. In Fig. 12 the slit-width correction has not been applied to theisochromatics, except for X= 1.804 ^i and X= 1.968 jjl (short upper-most graphs. Fig. 12), which… … 5 WATTS ENERGY 2. Isochromatics of Nernst glower.—In a preceding paper ^^ onthe selective emission of the Nernst glower the writer concludedthat because the spectrum was discontinuous at low temperaturesit must behave likewise at high temperatures (provided a largeenough dispersion could be…
