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.
The guillotine is a machine used to execute people by decapitation (chopping off their heads). A guillotine is made of a heavy blade attached to a rack, which moves up and down on a vertical frame. When the rack is let go, it will fall down and the blade will cut the convict's head off.
