then pass their light through a defraction grating.
Each element has a characteristic
pattern of wavelengths,
its spectrum, produced
by their spectroscope.
Bunsen and Kirchoff began
to systematically correlate
chemical elements and chemical compounds
with their spectra
linking absorption and emission lines,
and establishing
that spectroscopy can be used to analyze
trace chemicals in a sample.
Three laws
1
You get a continuous spectrum
from any incandescent material under high pressure.
2
You get an emission-line spectrum
from a hot gas under low pressure.
3
You get an absorption-line spectrum
from passing a continuous spectrum through a cool gas.
Analysis
I think I could
figure out anything,
given the right tools
and enough time.
Rocket scientist,

At least I’m persistent.
If you pay me well,
I’d buy an analyst’s couch,
and I’d be willing
for you to do the talking.
In addition to establishing the basis of analytic spectroscopy,
Robert Bunsen and Gustav Kirchhoff discovered caesium and rubidium using their spectroscope.
