Radio (lat. radiare, radio "emit, irradiate, radiate in all directions"; radius "beam") — a method of wireless transmission of messages over a distance by means of radio waves, as well as the field of science and technology related to the study of physical phenomena underlying this method, and its use for communication, sound broadcasting, image transmission, signaling, monitoring and control, detection of various objects and determining their location, and many other purposes
The term "radio" was first coined by the English chemical physicist William Crookes in 1873 (to explain the results of some chemical experiments), i.e. almost 20 years before the invention of radio
