Sound.
More information
After a modulated carrier signal has been received through the radio's aerial, the radio de-modulates it to release the live sound as picked-up from microphones in the radio studio (or was taken from recordings), which was then used to modulate the carrier signal at the transmitter.
De-modulation that is done by a radio receiver can be described very simply as "removing the carrier signal to produce the sound".
No, radio waves are transverse waves, meaning the oscillation of the wave is perpendicular to the direction of wave propagation. Longitudinal waves have oscillations parallel to the direction of wave motion.
No. Seismic waves are mechanical. Radio waves are electromagnetic.

Radio waves are electromagnetic radiation.
Radio Waves.
A radio wave is an electromagnetic wave. Electromagnetic waves are transverse waves.
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 are lower frequency.
Radio waves in electromagnetic waves/water waves
No difference at all. Radio waves are one of many types of electromagnetic waves.
Radio waves are a type of electromagnetic wave. They do not require a medium to travel through and can travel through a vacuum, unlike mechanical waves which require a medium, such as air or water, to propagate.
