1 Glossary: Absorption Spectrum: results from the ability of pigments to absorb incident electromagnetic radiation. Like the action spectrum, the parameter of interest (light absorbed) is plotted as a function of the wavelength of the radiation.arious chlorophylls and accessory pigments have characteristic absorption spectra. The action spectrum of photosynthesis relates to the relative electron-exciting effectiveness of different wavelengths of light.
Joseph Guillotine had never invented the device. He only proposed to find a mechanical and more human mean to carry death penalty to the National Assembly in 1789. The machine was invented by a surgeon-Antoine Louis-in 1792.
In its modern form, it was invented in 1792 by a parisian  surgeon named Antoine Louis and built by a piano-builder named  Tobias Schmitt. to be true, it was an improvemen â¦ t of an already  existing device.    Contrary to the common belief, Joseph Ignace Guillotin had not  invented the guillotine.
