almost everything emitts radiowaves.they are the weakest and therefore easiest to produce therefore being the most common form of radiation.
Free electrons emit radio waves when they are scattered by collisions with the heavier ions.

Energy. Radio is a type of electromagnetic wave which ossilates at a specific frequency.
Oscillating charges. (Electric current that goes back and forth periodically.)

they use radio waves to pick up some what satellite images or existance of things in space
The monitoring device is a radio transmitter that sends signals to the radio transmitter. Radio waves are a type of Electromagnetic waves.

The device has a transformer inside - which amplifies the mains power. The power is fed to an internal 'transmitter' - which sends high-frequency radio waves 'bouncing' around the oven's interior. The radio waves are part of the electromagnetic spectrum.
a device that converts radio waves to audio waves
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.
