See also:KUNDT, See also:AUGUST ADOLPH EDUARD See also:EBERHARD (1839-1894) , See also:German physicist, was See also:born at See also:Schwerin in See also:Mecklenburg on the 18-th of See also:November 1839. He began his scientific studies at See also:Leipzig, but afterwards went to See also:Berlin. At first he devoted himself to See also:astronomy, but coming under the See also:influence of H. G. See also:Magnus, he turned his See also:attention to physics, and graduated in 1864 with a thesis on the depolarization of See also:light. In 1867 he became privatdozent in Berlin University, and in the following See also:year was chosen See also:professor of physics at the See also:Zurich See also:Polytechnic; then, after a year or two at Wiirzburg,he was called in 1872 to See also:Strassburg, where he took a See also:great See also:part in the organization of the new university, and was largely concerned in the erection of the See also:Physical See also:Institute. Finally in 1888 he went to Berlin as successor to H. von See also:Helmholtz in the See also:chair of experimental physics and directorship of the Berlin Physical Institute. He died after a protracted illness at Israelsdorf, near See also:Lubeck, on the 21st of May 1894. As an See also:original worker Kundt was especially successful in the domains of See also:sound and light. In the former he See also:developed a valuable method for the investigation of aerial waves within pipes, based on the fact that a finely divided See also:powder—See also:lycopodium, for example—when dusted over the interior of a See also:tube in which is established a vibrating See also:column of See also:air, tends to collect in heaps at the nodes, the distance between which can thus be ascertained. An See also:extension of the method renders possible the determination of the velocity of sound in different gases. In light Kundt's name is widely known for his inquiries in anomalous See also:dispersion, not only in liquids and vapours, but even in metals, which he obtained in very thin films by means of a laborious See also:process of electrolytic deposition upon platinized See also:glass. He also carried out many experiments in magneto-See also:optics, and succeeded in showing, what See also:Faraday had failed to detect, the rotation under the influence of magnetic force of the See also:plane of polarization in certain gases and vapours.
