Lower frequency (between 30 and 3,000 kHz) vertically polarized radio waves can travel as surface waves following the contour of the Earth; this is called ground wave propagation. In this mode the radio wave propagates by interacting with the conductive surface of the Earth. The wave "clings" to the surface and thus follows the curv… WebApr 13, 2024 · Basically, every material affects the propagation of radio waves. Absorption That one's kind of obvious: radio wave hits medium (e.g. soil), gets absorbed. That's the reason you can't look through a piece of coal – light is just a wave at a high frequency, and coal absorbs light very well. cyclops turn signalsWebOct 6, 2024 · 1.
