“What I can’t understand,” said the young woman, “is how you can send out a wireless message when the wind is blowing so hard.”
If the operator had been even a 14-carat gentleman he would have told her that when he works the key a low pressure current of electricity is broken up into dots and dashes representing letters and that this intermittent current flowing through the coil of the transmitter is changed into high frequency oscillations by the spark; the oscillations then surge through the aerial wire and their energy is emitted from the aerial in the form of electric waves. These electric waves are exactly the same as light waves, except that they are very much longer, and both are transmitted by, in and through the ether. Hence the wind, which is air in motion, has nothing at all to do with it.
This would have been the real scientific explanation of how a message is sent and while it would, more than likely, have been as clear as mud to her young inquiring mind, still if she could not grasp the true explanation of how it works it would have been her misfortune and not the operator’s fault.
