I was thinking about designing and building a radio controlled submarine for fun but I am wondering if it will be able to pick up radio waves from up to 20 feet under fresh water. If anybody knows anything about this subject I would appreciate some feedback.
thanks, Mike

Yes, they do....sonar, for example.
The interface travel between water/air scatters the waves. You'd probably have to keep the antenna under water.

Yes Radio waves do. To give a more detailed explanation, Radio waves are part of the electromagnetic spectrum. visibile light is part of this spectrum also. The difference between "light" and radio waves is that the frequency or the wavelength in different. However, since water is a different type of medium than that of air, the Radio wave will travel at a different speed, although this speed is still extremely fast.

Yes they do. I once had a RC sub. Just remember to have some type of fail safe method to raise your model should it loose radio contact or have some other type of failure. You might also try a trick from the real submarine world and use a piece of floating wire for the antenna.

The first answer is right and the second answer is wrong. There are commercial RC subs you can buy and sonar is a sound wave, not radio.

yes they do
just remember snells law!!! :)
nsin(theta)air=nsin(theta)water
