Radio waves were discovered before the radio was invented.
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.

The unit for measuring radio waves, the hertz (Hz), is named after German physicist Heinrich Hertz, who made significant contributions to the study of electromagnetism and radio waves in the late 19th century.

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.
If you're asking, who invented radio, an Italian inventor named Marconi is generally credited with the invention of radio around the end of the Nineteenth century.A radio is not a player, it is a device consisting of a transmitter, which changes sound waves into radio waves that can travel great distances. The second part of a radio is called a receiver. It receives the radio waves the transmitter sends out and converts them back to audible sound.
Radio waves are electromagnetic waves occurring on the radio frequency portion of the electromagnetic spectrum.
by changing the amplitude or frequency of the radio waves.
Radio Waves - radio station - was created in 2010.
by changing the amplitude or frequency of the radio waves.
Radio and light waves are electromagnetic waves, sound waves are not.
