Radio waves my question.

The Radio waves humanity have been transmitting since the invention of radio, Will those Radio wave exit our solar system in the same state as they were when the left earth..?

If so How would we test this to find out..?

well think of it as shining a light into space, same thing just lower in frequency.

Its possible to bounce signals off the moon back to earth, radio amateurs have been doing it for years, you can even recieve the signal you sent

As for making it out of the solar system , i'm not sure! it would possibly end up so weak it would be indistinguishable from the background mush, but no reason why a stong enough focussed beam wouldn't span vast distance of space, the mars curiosity etc don't seem to have too much trouble.

Voyager 1 is leaving the solar system as we speak.
We are still in communication with it so yes radio waves can leave the system pretty much the same as when they left Earth.

But radio wave strength drops severly with distance. It's inversely proportional with the square of the distance.
I don't think we could communicate with it at twice the current distance. The signal would be just too weak.

So it's not likely that other species can hear our signals.

We see stars due to travel in a loss less medium.
This in answer to a student's question in optics class.

Gamma ray and other rays seem to also apply to the loss less theory.
I know radio signals are weak and we need amplification to hear the radio.

Traveling far away in a car can lose a signal.
The radio signal perhaps has different ways to transmit but should apply
to the loss less medium theory.

Tesla's waves were actually power waves. Mostly static that actuated through the medium.

Thank you guys, So it is very unlikely that anyone or anything could trace our radio waves back to this location out side of this solar system. Good to know.
