The electrical resonance of tuned circuits in radios allow individual frequencies to be selected.
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.
Lee de Forest helped popularize the new word in the United States—in early 1907 he founded the De Forest Radio Telephone Company, and his letter in the June 22, 1907 Electrical World about the need for legal restrictions warned that "Radio chaos will certainly be the result until such stringent regulation is enforced". Although its translation of the 1906 Berlin Convention used the terms "wireless telegraph" and "wireless telegram", by 1912 it began to promote the use of "radio" instead.
The term started to become preferred by the general public in the 1920s with the introduction of broadcasting.
The radio- prefix was later used to form additional descriptive compound and hyphenated words, especially in Europe.
For example, in early 1898 the British publication The Practical Engineer included a reference to "the radiotelegraph" and "radiotelegraphy", while the French text of both the 19 Berlin Radiotelegraphic Conventions includes the phrases radiotélégraphique and radiotélégrammes.
The term "radio" is derived from the Latin word "radius", meaning "spoke of a wheel, beam of light, ray".
It was first applied to communications in 1881 when, at the suggestion of French scientist Ernest Mercadier, Alexander Graham Bell adopted "radiophone" (meaning "radiated sound") as an alternate name for his photophone optical transmission system.
When she sent me pictures to thank me it was a clear day and the glass drop was clear. First, I will admit that I am a total weather geek, have been since I was a kid, and I'm a forest ecologist interested in weather and climate effects on natural systems.Tags: Adult Dating, affair dating, sex dating
