WebRadio waves are deflected in a number of ways as they move through the troposphere. For example, they may be reflected, refracted, or diffracted by air molecules through which they pass. As a consequence, radio waves can actually pass beyond Earth's optical horizon and, to an extent, follow Earth's curvature. WebOne is that radio waves are pulled and turn slightly because of gravity when they pass by large masses. The other exception is that radio waves can be reflected by certain …
