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.
He killed thousands of people, sending them to the guillotine, just because they still believed in the monarchial system Maximilien Robespierre wanted to get rid of so desperately. He killed everybody that thought differently than him. He was the creator of the reign of terror and was eventually sent to the guillotine himself in 1794 after the French turned against him when their eyes opened and say what he had done. He didn't even have a trial, and was beheaded faced upwards.
