ground wave radio signals travel along the earth's surface by inducing electrical currents in the ground, which help guide the wave forward. these low-frequency signals also diffract, or bend, around the curvature of the earth, allowing them to follow its contours up to typically effective up to a few hundred kilometers, depending on frequency and terrain. wet ground or seawater improves propagation; dry, rocky terrain worsens it.
