FRESNEL, AUGUSTIN - EXPOUNDING THE WAVE THEORY OF LIGHTBiblio.com

Mémoire Sur les couleurs développées dans des Fluides homogènes par la lumière polarisée. Presenté à l'Academie le 30 mars 1818 Mémoire sur la Réflexion de la Lumiere. Presenté à l'Academie le 15 novembre 1819. 2 Memoirs.

184644101Paris Victor Masson 1846. No wrappers as extracted from "Annales de Chimie et de Physique" Tome 17 Troisieme Série. Titlepage to tome 17. Pp. 172-199 a. 1 engraved plate pp. 316-338 textillustr. Brownspots to titlepage and some browspots to the second memoir. First editions of two importent memoirs on polarization and reflexion of light by "the founder of the new optics".The first paper takes on a central role in Fresnel's dealing with polarization in general and specially with chromatioc polarization and the explaining the phenomena that arises when light travels through crystals. The paper was read at the Academy on march 30 was not printed at the time as it disappeared and only turned up many years later around 1845 when it was found in the papers of Fresnel's brother. "On croyait ou Mémoire perdu. Il a été retrouvé dans les papiers de M. Léonor Fresnel frère de l'illustre académicien." Thus the offered paper is here PRINTED FOR THE FIRST TIME AND IN ITS FULL LENGHT.The second paper deals with reflection and explains the different phenomena seen when light is reflected from glassplates having two surfaces parallel or with curvature interference of reflected waves and the measure of their different wavelenghts all explained according to the wave theory of light. The paper offered is for the FIRST TIME PRINTED IN ITS FULL LENGHT as it only appeared in the résumé-form in 1820 "Résumé d'un Mémoire sur la Réflexion de la lumière" Annales de Chimie et de Physique tome 15 pp. 379-386."As it was Fresnel succeeded fully in attaining his explicit goal the establishment of the wave conception of light. Not long after his death scientific opinion definitely shiftedin favor of waves and opened up the pathway leading to the deeper insight of Maxwell. In broad context 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."

LORENZ, L (LUDWIG VALENTIN) - LIGHT IS IDENTICAL WITH ELECTROMECANICAL WAVESBiblio.com

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

186755371København 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."

185149596Paris Bachelier 1851. 4to. No wrappers. In: "Comptes Rendus Hebdomadaires des Séances de L'Academie des Sciences" Tome 33 No 13. With htitle and titlepage to tome 33. Pp. 329- 360 entire issue offered. Fizeau's paper: pp. 349-355. A stamp on upper right corner of title-page and a perforated stamp in lower margin of title-page. Clean and fine. First appearance of this paper the first announcment of Fizeau's results of his experiments with the velocity of light."It the paper is less famous for some reason than the failure of Michelson and Morley to detect the aether drag but NO LESS SIGNIFICANT. For it showed that the velocity of light increases in a medium according to the formula v 1 - 1/n2 where v is the velocity of the medium and n is the refractive index"Gillespie in "The Edge of Objecticity" p. 427. Fizeau shows that the velocity of light is higher in water flowing in the direction of the beam than that of light propagating in the direction opposite the direction of flow. The paper offered is the shorter announcement of the research the paper in full was published later in 1859 in "Annales de Chimie et de Physique". Albert Einstein later pointed out the IMPORTENCE OF THE EXPERIMENT FOR SPECIAL RELATIVITY.Fizeau's result was replicated by Albert Michelson and Edward Morley in 1886 repeated the experiment on a larger scale and confirmed Fizeau's results. and in 1914 it was confirmed by Pieter Zeeman. It was Arago in 1838 who suggested this "crucial experiment" to decide between the corpuscular and undulatory theories of light by comparing the speed of light in water and in air. It vindicated the undulatory position.It was shown by Hendrik Lorentz 1892 1895 that the experiment can be explained by the reaction of the moving water upon the interfering waves without the need of any aether entrainment. On this occasion Lorentz introduced a different time coordinate for moving bodies within the aether the so called Local time an early form of the Lorentz transformation for small velocities compared to the speed of light. In 1895 Lorentz went a step further and explained the coefficient by local time alone and without mentioning any interaction of light and matter. unknown

186249458Paris Mallet-Bachelier 1862. 4to. No wrappers. In: "Comptes rendus hebdomadaires des séances de l’Académie des sciences" Vol. 55 No 12 a. 21. Pp. 481--519 a. pp. 781-803. Entire issues offered. With title-page to vol. 55. Foucault's papers: pp. 501-503 a. pp. 792-796. Clean and fine. First printing of Foucault's famous experiments on the velocity of light with the description of his improved equipment the rotating mirror. Foucault's method was later developed by Michelson and Morley in their famous experiment in 1887."Foucault’s first experiment carried out in 1850 and written up in full in his doctoral thesis of 1853 was purely comparative; he announced no numerical values until 1862. Then with an improved apparatus he was able to measure precisely the velocity of light in air. This result significantly smaller than Fizeau’s of 1849 changed the accepted value of solar parallax and vindicated the higher value which Le Verrier had calculated from astronomical data. Foucault’s turning-mirror apparatus was the basis for the later determinations of the velocity of light by A. A. Michelson and Simon Newcomb."DSB.Leon Foucault used a similar method to Fizeau. He shone a light to a rotating mirror then it bounced back to a remote fixed mirror and then back to the first rotating mirror. But because the first mirror was rotating the light from the rotating mirror finally bounced back at an angle slightly different from the angle it initially hit the mirror with. By measuring this angle it was possible to measure the speed of the light. Foucault continually increased the accuracy of this method over the years. His final measurement in 1862 determined that light traveled at 299796 Km/s. Magee "A Source Book in Physics" p. 342 ff. and "Source Book in Astronomy" p. 282 ff. unknown
