The electrical resonance of tuned circuits in radios allow individual frequencies to be selected.The electromagnetic wave is intercepted by a tuned receiving antenna.However, this invention would not be widely adopted.
I run a Davis VP2 system that has been connected to the Weather Underground for over 18 years (KCTCOLEB1); we have a second Davis console on the dinner table.
However, "wireless" included a broad variety of related electronic technologies, including electrostatic induction, electromagnetic induction and aquatic and earth conduction, so there was a need for a more precise term referring exclusively to electromagnetic radiation.
The first use of radio- in conjunction with electromagnetic radiation appears to have been by French physicist Édouard Branly, who in 1890 developed a version of a coherer receiver he called a radio-conducteur.
Radio is the technology of using radio waves to carry information, such as sound, by systematically modulating properties of electromagnetic energy waves transmitted through space, such as their amplitude, frequency, phase, or pulse width.
When radio waves strike an electrical conductor, the oscillating fields induce an alternating current in the conductor.
