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 first commercially available GUI, called PARC, was developed by Xerox. It was used by the Xerox 8010 Information System, which was released in 1981. After Steve Jobs saw the interface during a tour at Xerox, he had his team at Apple develop an operating system with a similar design. Apple's GUI-based OS was included with the Macintosh, which was released in 1984. Microsoft released their first GUI-based OS, Windows 1.0, in 1985.
