An instrument for measuring the wavelength of a radio-frequency wave.

OBS

The following are representative types: resonant-cavity, resonant-circuit, and standing-wave.

OBS

The standing-wave type is exemplified by a Lecher wire. Wavemeters may also be classified as (1) transmission type in which the resonant element and the detector are so arranged as to give a maximum response at resonance; and (2) suppression (absorption or reaction) type, which provide minimum response at resonance.

OBS

wavemeter: term and definition standardized by the Institute of Electrical and Electronics Engineers .

OBS

See also "frequency meter"; "frequency counter".

  • Ondes radioélectriques
DEF

Fréquencemètre gradué en longueurs d'onde.

OBS

En radioélectricité, on se sert de l'ondemètre à absorption : c'est un circuit composé d'une bobine en forme de boucle et d'un condensateur variable, dans lequel l'onde électromagnétique induit une force électromotrice. La valeur maximale de la force électromotrice, ou du courant, obtenue à la résonance, est indiquée par le maximum d'éclat d'une lampe au néon ou d'une lampe à incandescence.
