| 7B11.10 | sodium absorption/emission | PIRA 500 | |
| 7B11.10 | sodium absorption/emission | 7C11.10 | A TV camera shows the Na doublet from a spectrometer in both emission and absorption. |
| 7B11.10 | emission and absorption of sodium | Oo-4 | A
grating spectrometer that resolves the sodium d lines is used to show emission
by a salt flame and absorption of white light by the flame. |
| 7B11.11 | Monochromator | AJP 35(11),1032 | Design of a simple monochromator with folded optics that will resolve 1 angstrom lines. |
| 7B11.12 | sodium emission/absorption | L-107 | Illuminate half a slit with a sodium flame, half with sunlight from a heliostat. Compare emission and absorption lines. |
| 7B11.13 | sodium absorption and emission | 39-1.9 | A
projection system is aligned so both emission and absorption lines of sodium
are visible from an arc with one electrode drilled and filled with anhydrous
sodium carbonate. |
| 7B11.15 | dark line sodium spectra | Oo-3 | White
light is passed through a concrete block containing a second arc that vaporizes
sodium and the spectrum produced shows the sodium d line. |
| 7B11.15 | sodium absorption lines | 39-1.4 | White light is passed through sodium flames before being dispersed by a prism. |
| 7B11.16 | sodium flame | AJP 31(12),945 | Place a Pyrex test tube at 45 degrees with the bottom in the hottest part of the flame. |
| 7B11.16 | sodium absorption | L-108 | Three methods of burning sodium in an arc and generating enough sodium vapor to show a strong absorption line. |
| 7B11.17 | flame salts | PIRA 1000 | |
| 7B11.17 | flame salts | Disc 25-07 | The colors of different flame salts are observed. |
| 7B11.19 | imitation line spectra | L-103 | While
projecting a slide of the continuous spectrum, insert another plate with
lines drawn on representing the absorption spectrum of a gas. |
| 7B11.20 | spectral absorption by sodium | PIRA 500 | |
| 7B11.20 | sodium absorption cloud | AJP 30(9),654 | A cloud of black smoke seems to form when vapor from flame heated salt is illuminated with a sodium lamp. |
| 7B11.23 | two lamp flame absorption | AJP 36(3),ix | Use two lamps (He and Na) with a single condenser and target to provide a reference with the sodium flame absorption. |
| 7B11.24 | absorption spectra | A-70 | Several methods for producing sodium vapor and passing white light through. |
| 7B11.25 | flame absorption projected | PIRA 1000 | |
| 7B11.25 | flame absorption projected | 39-1.7 | The light from an arc lamp is focused on a Bunsen burner flame on the way to being projected on the screen. |
| 7B11.25 | spectral absorption by sodium vapor | Disc 25-02 | Sodium flame looks dark when illuminated with sodium light. |
| 7B11.30 | mercury vapor shadow | PIRA 1000 | |
| 7B11.30 | mercury vapor shadow | Oo-2 | Mercury vapor illuminated with a mercury lamp casts a shadow on a Willemite screen. |
| 7B11.30 | mercury vapor shadow | 39-1.5 | A UV lamp shines on a zinc sulfide screen while mercury vapors waft from a heated watchglass. |
