the word "radio" stands for which phrases.?

Question

I mean is the word radio abreviation of a few words ? if so,.please tell me the full phrase.

Answer 1

Radio is not an acronym. Radio is abstracted from earlier combinations such as radiophone (1881) and radio-telegraphy (1898). The word radio is therefore derived from radio-, combined form of *radiation*. This makes sense because a radio receives radio waves, which are a form of electromagnetic *radiation*.

RADAR, on the other hand, *is* an acronym, and is based on radio. It comes from the letters of RAdio Detecting And Ranging.

Answer 2

What Does Radio Stand For

Answer 3

RADIO stand for Radiation And Detection of Information and Observation

Answer 4

Radio waves are a form of electromagnetic radiation, created whenever a charged object (in normal radio transmission, an electron) accelerates with a frequency that lies in the radio frequency (RF) portion of the electromagnetic spectrum. In radio, this acceleration is caused by an alternating current in an antenna. Radio frequencies occupy the range from a few tens of hertz to three hundred gigahertz, although commercially important uses of radio use only a small part of this spectrum.

Originally, radio technology was called 'wireless telegraphy', which was shortened to 'wireless'. The prefix radio- in the sense of wireless transmission was first recorded in the word radioconductor, coined by the French physicist Edouard Branly in 1897 and based on the verb to radiate. 'Radio' as a noun is said to have been coined by advertising expert Waldo Warren (White 1944). The word appears in a 1907 article by Lee de Forest, was adopted by the United States Navy in 1912 and became common by the time of the first commercial broadcasts in the United States in the 1920s. (The noun 'broadcasting' itself came from an agricultural term, meaning 'scattering seeds'.) The American term was then adopted by other languages in Europe and Asia, although Britain retained the term 'wireless' until the mid-20th century. In Chinese, the term 'wireless' is the basis for the term 'radio wave' although the term for the device that listens to radio waves is literally 'device for receiving sounds'.
