The inverse square law states that the signal strength of an RF wave is inversely proportional to the square of the distance from the source. This means that as the distance from the transmitter increases, the signal strength decreases rapidly.

I think the answer might be the inverse square law, but I'm not completely sure. It seems to fit with how signal strength decreases over distance.
