antinode|ˈæntɪnəʊd| [f. anti-1 2 + node 6.] A point or line of maximum disturbance in a vibrating body, a region of maximum amplitude between nodes: for spec. applications see quots.
1882J. D. Everett Vibratory Motion & Sound v. 51 Comparing together the four positions of the string..points A, C, and A1 remain permanently at rest, and the points B and D midway between them undergo the largest displacement... The points of permanent rest, A, C, and A1 are called nodes and the points of maximum displacement, B and D, antinodes. 1889Cent. Dict., Antinode, a point of a vibrating string where the amplitude of vibration is greatest. 1910Hawkins' Electr. Dict. 14/2 Anti-nodes, the points in wave motion which vibrate through the greatest amplitude, half-way between the points at rest, called nodes. 1926Gloss. Terms Electr. Engin. (B.S.I.) i. 199 Antinode, in a system which has a non-uniform distribution of R.M.S. current or voltage, any point at which the R.M.S. value is at its maximum is called an antinode of current or of voltage respectively. 1930Engineering 29 Aug. 255/2 Measurement of wavelength by noting successive current antinodes along the wires. 1959Chambers's Encycl. VIII. 554/1 These points are called nodes. At the intermediate points..the ether particles oscillate with maximum amplitude; these points are called antinodes. |
