a galvanometer with strong field, in which the mass of the moving part is very small and frequency of vibration very high. -- Os`cil*lo*graph"ic (#), a.

ernating current into an alternating current of a different number of phases and the same frequency.

An instrument for measuring sounds, as to their intensity, or the frequency of the vibrations.

The quality or state of being shy. [Written also shiness.] Frequency in heavenly contemplation is particularly important to prevent a shyness bewtween God and thy soul. Baxter.

A disruptive discharge between a conductor traversed by an oscillatory current of high frequency (as lightning) and neighboring masses of metal, or between different parts of the same conductor.

imilar or analogous to the telephone, but not held to the ear. The pitch corresponds with frequency of alternation of current.

A transformer without iron, for high frequency alternating or oscillating currents; an oscillation transformer.

ities, and producing different impressions on the retina according to their amplitude and frequency, the sensation of brightness depending on the former, that of color on the latter. The undulations are supposed to take place, not in the direction of propagation, as in the air waves constituting sound, but transversely…

at of Guglielmo Marconi, patented in March, 1897. Marconi employed electric waves of high frequency set up by an induction coil in an oscillator, these waves being launched into space through a lofty antenna. The receiving apparatus consisted of another antenna in circuit with a coherer and small battery for operating…
