Paperback. Condizione: New. Print on Demand. This book introduces a new method for determining the wavelengths of light by relying on interference patterns created by passing light through a diffraction grating. The author's technique significantly improves upon the existing method by reducing errors and increasing accuracy. They also analyze Fraunhofer's groundbreaking work on the subject, providing a comprehensive overview of this field of study. The book's detailed explanations and meticulous research make it an essential resource for scientists and researchers interested in the study of light and optics. It builds upon the foundation laid by Fraunhofer, offering a deeper understanding of the principles governing the behavior of light and its interactions with matter. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item.

Förhandl." erschienenen Arbeit, hier mit Zusätzen versehen. - "After 1861 Angström intensively studied the spectrum of the sun, noting the presence of hydrogen in the solar atmosphere and confirming the probable existence there of a number of other elements. In 1868 he published his monumental 'Recherches sur le spectre solaire', which contained an atlas of the solar spectrum with measurements of the wavelenghts of approximately a thousand lines determined by the use of diffraction gratings. Angström expressed his results in units of one ten-millionth of a millimeter - a unit of length that has been named the angstrom unit in his honor" (DSB). - Stempel auf Titel.

(Upsal, C.A. Leffler, 1860). 4to. Orig. printed wrappers. Extracted from "Actes de la Soc. Roy. des Sciences d'Upsala", Series 3ieme. T. III. Pp. (51-) 72. This extract has the orig. printed wrappers from Tome III. First edition of Ångström's importent paper on the transformation of heat through materials. Angstrom determined the conductivity of the material of a bar by periodically heating and cooling it. The bar was heated and cooled periodically by passing steam and water at regular intervals through a chamber at one end of the bar . In this way, the temperature at points along the bar fluctuate periodically and on account of surface radiation the temperature amplitude diminishes as the distance from the region of supply increases.In 1868, Ångström created a spectrum chart of solar radiation that expresses the wavelength of electromagnetic radiation in the electromagnetic spectrum in multiples of one ten-millionth of a millimetre, or 1×10-10 metres. This unit of length later became known as the ångström, Å.

Upsala, Berling, 1875. Uncut in original printed wrappers. The entire volume of "Nova Acta Regiæ Societatis Scient. Upsaliensis." Seriei Tertiæ. Vol. IX, Fasc. II. The memoir: 34 pp. and 2 large folded plates. First printing."A work on the spectra of the metalliods, which was begun some years previously, was completed by Tobias Robert Thalén, who actively assisted Ångström for many years, and was published in 1875. In opposition to the view that a given chemical element had a multiplicity of spectra, depending upon conditions, Ångström remained a strong defender of the opinion that each chemical element had a single characteristic spectrum that remained essentially unchanged."

Leipzig, Johann Ambrosius Barth, 1862. Without wrappers as issued in "Annalen der Physik und Chemie. Hrsg. von J.C. Poggendorff", Vierte Reihe Bd. 27 (117), Stück Zwei, No. 10. The entire issue offered. Titlepage to vol. 27. Pp. 193-352 a. 1 engraved plate. Ångströms paper: pp. 290-302. First appearance in German of Ångström's famous paper in which he announced the discovery of hydrogen in the atmosphere of the sun and in which he also confirmed the probable existence of of other elements there. The paper appeared in "Oefversigt af K. Vet. Acad. Förhandl." in 1861. The German paper here is expanded. At the same time it was translated into English and publishe as "On the Fraunhofer Lines Visible in the Solar Spectrum".Ångström was one of the early formulators of the science of modern spectroscopy" he wrote extensively on terrestrial magnetism, the conduction of heat, and especially spectroscopy. He published a monumental map of the normal solar spectrum that expressed the length of light waves in units of one ten-millionth of a millimeter, a unit of length now known as the angstrom. He discovered that hydrogen is present in the sun's atmosphere, and he was the first to examine the spectrum of the aurora borealis.

Condizione: Good. Uppsala, Wahlström & Låstbom (1843). 4:o. (4),+ 8; (2),+ 16; (2),+ 17-24 s. Häftade och oskurna, delvis tagna ur band. Tre häften. Marklin 3-5. Allt som utkom. Respondenter var Daniel H. Forssberg, Andreas Nordensvan och Abraham Nensén, alla tre från Norrland. Anders Jonas Ångström (1814-74) kom från Medelpad. Han diputerade på en avhandling i fysik 1839 ?Om conisk refraktion? Han kunde dock inte räkna med en snabb akademisk karriär inom fysik, då den professorstolen nyligen blivit tillsatt, utan sadlade om till astronomin. Han blev efter framläggandet av denna avhandling 1843 utnämnd till observatör vid Uppsalaobservatoriet och inriktad på professuren i astronomi. Situationen på professorsstolarna förändrades dock ånyo och 1858 blev han ändå professor i fysik, och som sådan så småningom världsberömd. Softcover / Paperback.
