Example Of Wireless Telegraphy

Likewise, in the case of the wireless telegraphy, the electric energy

produced by the sending instrument is transformed into subtle and finer

etheric waves, which travel to the receiving instrument, and are there

transformed into electric waves, the latter producing physical changes

in the receiving apparatus which enable them to be read by the observer.

In the case of wireless telephony there is still more complex process of

transformation, as follows: the speaker conveys sound vibrations into

the instrument; these are transformed into electric vibrations; and the

latter into the etheric vibrations which travel through space to the

receiver. Reaching the receiver, the etheric vibrations are transformed

into ordinary electric vibrations, and these in turn into sound waves

capable of being sensed by the listener.
