TitleManuscript, 'Electrical interference phenomena somewhat analogous to Newton's rings, but exhibited by waves passing along wires of which a part differs from the rest' by Edwin Henry Barton
DescriptionBarton writes: 'In 1891 Mr V Bjerknes showed how to measure the wavelength and primary damping of the electrical oscillations in a Hertzian primary conductor by the use of a special electrometer and long parallel wires along which induced oscillations were propagated. This form of Hertzian secondary conductor, in which the wires are far too long to be in resonance with the primary oscillator, may, hereafter in this paper, be referred to as “the long secondary” or simply “the secondary.” During the following session Herr von Geitler found that, if the wires at any part of the long secondary were either (1) Replaced by others thicker or thinner than the normal wires, or (2) Arranged nearer together or further apart than the normal distances, then in any of these cases, a partial reflection of the electrical waves occurred at such place of change in the wires.'

Annotations in pencil and ink. Includes four diagrams and graphs relating to experimental observations.
