What reading level is A Spectrographic Study By Means of a Grating Replica Spectroscope And the Dete book?
To quickly assess the difficulty of the text, read a short excerpt:
000, 51. 060, etc. , when the line ^5179 is set on 40. 000.
THE COMPARATOR METHOD.
Now to convert these numbers into wave lengths, a chart must be drawn upon cross section paper. Copper has in its spec- trum several prominent lines which are easily recognized. There are three lines in the red, ^5218, ^5153, and ^5105, which read on the comparator 39. 025, 40. 645, and 41. 800 respectively; two lines in the green, ^4651 and '-4275, which read on the comparator 52. 900 and 62. 340; two lines in t...he violet, ^4062 and ^4022, on the comparator 67. 720 and 68. 710. There occur also, several iron lines with the copper in the spectrum, as the copper was not pure; and these assist in plotting the curve.
A piece of cross section paper is taken which has along one co- ordinate, the wave length numbers, and along the other the com- 12 parator scale numbers. (Fig. 3. ) As the measurement of the plate commenced in the red, the comparator numbers read up, while the wave lengths read down. A place is now found on the chart along the wave length co-ordinate for ^5218, and along the comparator scale co-ordinate 39.
