The ones we call "radio waves".
That's the electromagnetic spectrum between maybe roughly speaking 10 KHz to 300 GHz.,
or wavelengths between 1 mm to 30 km.
Electromagnetic waves carry radio, television, and telephone information.

Radio waves are the type of electromagnetic wave that carries television and radio signals. They have longer wavelengths than microwaves and shorter wavelengths than infrared waves.
Communications Satellites ************************ Electro-magnetic waves. Carrier waves.
Your landline carries the voice/data on copper wires. A mobile uses radio waves but they are a different frequency from that used to broadcast TV.
by changing the amplitude or frequency of the radio waves.

Both radio waves and tv waves are electromagnetic waves. So both have the same speed in vacuum. Of course radio waves are of lower frequency compared to that of tv waves.
Is it true that radio waves carry information from a broadcasting station to your radio or television
