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.
Primitive ancestors of the guillotine were used in Ireland, England and Italy in the 14th and 15th Centuries. Several known decapitation devices such as the Italian Mannaia, the Scottish Maiden, and the Halifax Gibbet are well documented and may pre-date the use of the French guillotine by as much as 500 years. The following deals mostly with the modern guillotine from the late 18th Century until today.
