Guglielmo Marconi (Marchese Guglielmo Marconi), an Italian inventor, proved the feasibility of radio communication. He sent and received his first radio signal in Italy in 1895. By 1899, he flashed the first wireless signal across the English Channel, and two years later received the letter "S", telegraphed from England to Newfoundland. This was the first successful trans-Atlantic radiotelegraph. Wikipedia has a good article on this Nobel Prize winner, and a link is provided.
no, mechanical waves are not radio waves
Radio waves ARE electromagnetic waves.
Radio waves are electromagnetic waves that carry energy. When these waves are absorbed by the radio's antenna, they induce electrical currents in the circuitry of the radio. This process allows the radio to convert the energy from the radio waves into sound, enabling us to hear broadcasts. However, radio waves themselves do not heat; it is the conversion of that energy into electrical signals that allows the radio to function.
Radio waves are electromagnetic waves. The radio waves have the longest wavelengths in the electromagnetic spectrum. A radio wave has a much longer wavelength than does visible light. We use radio waves extensively for communications.
Radio waves were discovered before the radio was invented.

Transverse. Radio waves are electromagnetic waves, which are transverse.
No. Radar waves are one category of radio waves. Think of all the radio waves that are all around you right now . . . AM radio, FM radio, police and fire radio, highway patrol radio, taxi radio, television picture and sound radio waves, cellphone radio waves, garage-door-opener radio waves, bluetooth radio waves, WiFi waves, microwaves ... and you can't see any of them ! Radar waves can easily be there in the group.
by changing the amplitude or frequency of the radio waves.
Radio waves are electromagnetic waves occurring on the radio frequency portion of the electromagnetic spectrum.
Radio Waves - radio station - was created in 2010.

Radio and light waves are electromagnetic waves, sound waves are not.

No, electromagnetic waves that are felt as heat are called infrared waves, not radio waves. Radio waves have lower frequencies and longer wavelengths than infrared waves.
