sure, radio waves can range anywhere from the extremely low (ELF) freq of 30 hZ to ultrahigh freq (UHF) of about 3 GhZ (3,000,000,000 hZ). The range you're looking at is between ELF and very low freq (VLF) of 30 khZ. See the link below for a full list of frequencies and the associated values.
However the difference between radio waves and sound waves is that radio waves is actually part of the electromagnetic spectrum (light) whereas sound waves are caused by the movement or vibration of particles.

Yes. In fact, some of the very early garage door openers operated at about 20KHz. If you can put out enough power at that frequency, you can communicate under water and through the earth... that's how the Navy communicates with their submarines when they are under water... but the power is very hard to develop at RF frequencies and the antenna farms are miles long and truly impressive to see.

no radii waves are much higher frequency like the AM FM and even the bands that I'm aware of like cb,ham
I don't think they can. AM staitions are in kiloHz so it sounds like they would that's a very interesting question I'm gonna look into this.

It wont radiate far
