The spike toward the left hand side of the spectrum is probably the 4.3 µm resonance frequency of hot CO<sub>2</sub> characteristic of burning hydrocarbons (see [http://en.wikipedia.org/wiki/Flame_detection#Emission_of_radiation here)]. Given the size of the spectrum and its positioning, this represents a fireplace at which the characters are warming themselves against the winter chill. |
In the right of the comic appear some spectra arranged in the form of a Christmas tree. There are 3 different spectra in this "Christmas tree": | In the right of the comic appear some spectra arranged in the form of a Christmas tree. There are 3 different spectra in this "Christmas tree": | ||

− | In the branches there are two simpler spectra repeated at various places, one with a peak in the green zone, representing a green light source, and other with a peak in the red zone, representing a red light source. Both of these represent the tradition of putting colorful decoration in the tree, in this case apparently red and green colored Christmas lights. | + | In the branches there are two simpler spectra (repeated at various places), one with a peak in the green zone, representing a green light source, and other with a peak in the red zone, representing a red light source.
