Detailed explanation-2: -The receiver was called a wireless because there were no wires linking to the the transmitting station. It was called radio because the transmitting station radiated electromagnetic waves.
Detailed explanation-3: -Prior to the 1920s the radio was primarily used to contact ships that were out at sea. Radio communications were typically achieved by the use of Morse code messages. This was of great benefit to vessels in the water, particularly during emergency situations.
Detailed explanation-4: -The word radio became popularized in the early 20th century with the development of different radio-based technologies. The word itself originates from the Latin ‘radius’, meaning ‘ray’ or ‘beam’.
