She feels the vibrations and understands what is said to her.
We find that this dissipation, although undoubtedly going on, proceeds with extreme slowness, so that the vibrations pass their energy on to the ether as rapidly as they acquire it, and the " normal state " is never established.
The condenser method of making oscillations is analogous to the production of air vibrations by twanging a harp string at short intervals.
Vibrations increase in rapidity as a note rises and decrease as it falls.
Considering the time at which he wrote, Reis seems to have understood very well the nature of the vibrations he had to reproduce, but he failed to comprehend how they could be reproduced by electricity.
