August Kundt (1839 - 1894) |
| German
physicist who developed a method for determining the velocity of sound
in gases and solids. Kundt studied at the University of Leipzig but
afterward went to the University of Berlin. In 1867 he became an instructor
at Berlin, and in the following year he became professor of physics
at the Zürich Polytechnic. In 1872 he was called to Strasbourg,
where he was one of the founders of that city's Physical Institute.
In 1888 he succeeded to the chair of experimental physics and the
directorship of the Berlin Physical Institute. In his experiments
on sound, Kundt dusted the interior of a tube with a finely divided
powder to show the position of the nodes of the sound waves, thereby
determining their wavelength. He also studied the anomalous dispersion
of light in liquids, vapours, and metals. In his work with magneto-optics,
he showed the rotation, under magnetic influence, of the plane of
polarization in certain gases and vapours. © 1999-2001 Britannica.com Inc. |
