This letter was shown by Arago to Fresnel, who at once saw that it presented the true explanation of the non-interference of beams polarised in perpendicular planes, and that the latter effect could even be made the basis of a proof of the correctness of Young's hypothesis" for if the vibration of each beam be supposed resolved into three components, one along the ray and the other two at right angles to it, it is obvious from the Arago-Fresnel experiment that the components in the direction of the ray must vanish" in other words THAT THE VIBRATIONS WHICH CONSTITUTE LIGHT ARE EXECUTED IN THE WAVE-FRONT.""

But light waves, because of their transverse vibrations, are more complex than sound waves. Light can assume different forms of planes of vibration as well as different intensities. Using the same spectroscopic apparatus as in the preceeding experiment, Fizeau and Foucault observed the interaction of two rays produced by passing a single polarized ray through a birefringent crystal. In this case, instead of obtaining alternating bands of light and dark, they obtained bands of light periodcally polarized in different planes of vibration.""(DSB V, p. 19).‎

‎First appearances of this groundbreaking series of papers and memoirs in which Fresnel established the scientific basis for the wave theory of light and gave the theoretical framework for explaining, in the context of his theory of the transversal nature of lightwaves, the phenomena of double refraction, refraction, dispersion, polarization, interference, diffraction patterns, diffraction fringes as light spreads around objects, etc. He developed mathematically the hypothesis of the wave nature of light and he demonstrates its conformity with experience. His study of light was a dynamic interplay between theory and observation, between mathematics and experiment. - The offered series also comprises the contributions from Arago and the rapports from The French Academy's committees by Ampère, Biot and Fourier - see below nos. 6,11,14,15,a.nd 18.""From the point of view of method, his investigations extended from the manual operations of the laboratory to the most abstract mathematical analyses. Few physicists since Newton had been so versatile.""(Silliman in ""Historical Studies in the Physical Sciences"", vol. 4, p. 155.).""The wave-thory at this time was still encumbered with difficulties. Diffraction was not satisfactorily explained" for polarization no explanation of any kind was forthcoming the Huygenian construction appeared to require two different luminiferous media within double refracting bodies and the universality of that construction had been impugned by Brewster's discovery of biaxial crystals. The upholders of the emission theory, emboldened by the success of Laplace's theory of double refraction, thought the time ripe for their final triunph and as a step to this, in March 1817 they proposed Diffration as the subject of the Academy's prize for 1818. Their expectation was disappointed" and the successful memoir afforded the first of a series of reverses of which, in the short space of seven years, the corpuscular theory was completely owerthrown. The author was Augustin Fresnel...""(Whittaker ""A History of the Theories of Aether & Electricity"", vol. 1, p.107 ff.).""This concept of transverse waves met with the greatest hostility from the scientists of the day, who could not imagine an extremely fluid and rarified ether which at the same time possessed the mechanical properties of a rigid body. Even Arago admitted that he could not follow the exuberant engineer in his ideas. ButFresnel was convinced that at last he had the key to many mysteries, and with his model of waves he gave a full clarification of the phenomena of polarization. With insuperable precision he explained a long series of extremely complicated experiments, such as those of chromatic polarization that Arago himself had discovered by chance in 1811, and which the followers of Newton could not explain in spite of all their efforts. Following this line Fresnel reached the synthesis which is his masterpiece....we must recall the final interpretation that he gave of the famous phenomenon of partial reflection by transparent surfaces, that simple phenomenon which until then had puzzled Grimaldi, Newton, and Huygens, and which in Malus's experiments had unexpectedly acquired a special importencee as it had been compared to the great mystery of double refraction.""(Ronchi ""The Nature of Light"", p. 255 ff.).Comprising:1.

His methods of calculation utilized the principles of both Huygens and Young and he summed the effects due to different portions of the same primary wave-front. He demonstrates that the transverse wave theory of light explains the observed phenomena of reflection, refraction, interference, polarization, difraction patterns, diffraction fringes etc., making a strong case for the theory of the transverse nature of light waves. The memoir records also Fresnel's famous mirror-experiment.""In broad contect Fresnel's work can be viewed as the first successfull assault on the theory of imponderables and a major influence on the development of nineteenth-centurty energetics."" (DSB V, p. 171).""Augustin Fresnel seems to have adopted a wave theory of light from the very beginning of his studies. His first paper, presented to the Academy...in October 1815, and entitled ""La Diffraction de la Lumiere"" (the paper offered), was written after a long correspondance with Arago, who had promised Fresnel his full support. ""The wave theory"" Fresnel wrote, ""is well suited to explaining the complicated propagation of light phenomena, and since, as we know from the case of sound, waves can surcomvent obstacles, I decided to make a study of shadows.....It is because they cross in regions common to them both that two pencils of rays can produce fringes. hence it follows that the vibrations of rays which cross at very small angles can cancel out whenever crests of one correspond to the throughs of the other.""The voume contains further a notable paper by AMPÈRE ""Bestimmung der krummen Fläche der Lichtswellen in einem Mittel, dessen Elasticität verschieden ist nach den drei Hauptrichtungen, d.h. nach debjenigen, in welchem die von der Elasticität erregte Kraft in desselben Richtung wirkt, in der die Theilchen dieses Mittels verschoben wurden.""

‎Om Identiteten af Lyssvingninger og elektriske Stømme. (On the Identity of the Vibrations of Light with electrical Currents).‎

‎(København, 1867). Contemp. marbled clothbacked boards. Titlelabel with gilt lettering on upper cover. Pp. 26-45. Extracted from ""Oversigt over det Kgl. danskeVidenskabernes Selskabs Forhandlinger 1867, Nr. 1"".‎

‎Extremely scarce first edition of the paper in which Lorenz, independent of Maxwell, stated that light is electromechanical in nature, probably inspired by his former teacher H. C. Oersted, the discoverer of electromagnetism and professor at the Polytechnic College, he aimed at unifying the forces of nature without introducing new physical hypotheses. ""The idea that the various forces in nature are merely different manifestations of the one and same force has proved itself more fertile than all physical theories"".Most impressive of all Lorenz’ achievements in optics is his electromagnetic theory of light, developed in a relatively unknown paper of 1867, two years after Maxwell’s famous paper on the same subject. At that time Lorenz did not know Maxwell’s theory, and his own approach was quite different. Lorenz’ electromagnetic theory of light can be described briefly as an interpretation of the light vector as the current density vector in a medium obeying Ohm’s law. This paper contains the fundamental equations for the vector potential and the scalar potential or - for the first time - the corresponding retarded potentials expressed in terms of the current density vector and the electrical charge density. The concept of retarded potentials had already been introduced in an earlier paper by Lorenz in connection with research on the theory of elasticity. He found that the differential equation for the current density vector was the same as his fundamental wave equation for the light vector, completed with a term which explains the absorption of light in conducting media, and that his theory led to the correct value for the velocity of light."" (Mogens Pihl in DSB).The paper was published in English, 1867 ""On the identity of the vibrations of light with electrical currents."" (Philosophical Magazine 34: 287-301) and also in German in ""Annalen der Physik""‎

‎"MAJORANA, Q. - PROVING THAT THE SPEED OF LIGHT IS INDEPENDENT OF ITS SOURCE.‎

‎Démonstration experimentale de la constance de vitesse de la lumiére réfléchie par un miroir en mouvement.‎

‎(Paris, Gauthier-Villars), 1917. 4to. No wrappers. In: ""Comptes Rendus hebdomadaires des Séances de L'Academie des Sciences"", tome 165, No 14. Pp. (417-) 448. (Entire issue offered). Majorana's paper: pp. 424-428. A stamp in upper right corner of the first page.‎

‎First apperance of Majorana's paper which was the first experimentally to prove the speed of light as set forth by Einstein in his special relativity theory. Majorana was critical to Einstein's relativity, and he therefore tried to prove experimentally that the postulate of the speed of light was wrong. His experiments turned out otherwise, and he hereby proved Einstein's postulate that the speed of light was independent of the velocxity of its source.‎

‎"RITTER, (JOHANN W.). - THE DISCOVERY OF ""CHEMICAL RAYS"" - ULTRAVIOLET LIGHT AND RADIATION.‎

‎Announcing his discovery of ultraviolet light ""Von den Herren Ritter und Bückmann. - - Am 22sten Febr. habe ich auch auf der Seite des Violetts im Farbespectrum, ausserhalb desselben, Sonnenstrahlen angetroffen....‎

‎Halle, Rengerschen Buchhandlung, 1801. Without wrappers as published in ""Annalen der Physik. Herausgegeben von Ludwig Wilhelm Gilbert"", Bd. 7, Viertes Stück. The entire issue offered (=Heft 4). Pp. 387-528. Ritter's announcement p. 525. With titlepage to volume 7. Clean and fine. Titlepage a bit shavedin inner margin.‎

‎First printing of Ritter's announcement of his discovery of ultraviolet light in a halfpage letter addressed to Gilbert's Annalen. With that discovery, it became clear that visible light represents no more than a fraction of a continous spectrum.A year earlier, in 1800, William Herschel discovered infrared light. This was the first time that a form of light beyond visible light had been detected. After hearing about Herschel's discovery of an invisible form of light beyond the red portion of the spectrum, Ritter decided to conduct experiments to determine if invisible light existed beyond the violet end of the spectrum as well. He had heard that blue light caused a greater reaction in silver chloride than red light did. Ritter decided to measure the rate at which silver chloride reacted to the different colors of light. He directed sunlight through a glass prism to create a spectrum. He then placed silver chloride in each color of the spectrum and found that it showed little change in the red part of the spectrum, but darkened toward the violet end of the spectrum. Johann Ritter then decided to place silver chloride in the area just beyond the violet end of the spectrum, in a region where no sunlight was visible. To his amazement, this region showed the most intense reaction of all. This showed for the first time that an invisible form of light existed beyond the violet end of the visible spectrum. This new type of light, which Ritter called Chemical Rays, later became known as ultraviolet light or ultraviolet radiation (the word ultra means beyond). - Parkinson, Breakthroughs: 1801 P.‎

‎First appearance of this importent paper, the results of which Maxwell later used as a crucial support for his electromagnetical theory of light.""...The velocity of light c were measured by W. Weber and R. Kohlrausch in 1855 (the paper offered). They used an electrometer to determine the charge of a condnsor in electrostatic units, and a ballistic galvanometer to measure the same charge in electrodynamic units. The resulting value for c was in good agreement with that obtained by Fizeau in 1849, and Maxwell accordingly felt entitled to identify light and electromagnetic vibrations. This conclusion recalls Newton's identification of gravity with universal attraction: it was not only because they obeyed the same formal law, but also because both led to the same mathematical results, that Newton saw fit to combine them.""(Taton, Réne in ""History of Sciencein The Nineteenth Century"", p. 163).‎
