At most microwave (subset of radio) frequencies water acts like a mirror, completely reflecting the wave. This is exactly why submarines are completely invisible to radar and one must use sonar to track them. So no penetration.
WebAnswer (1 of 3): This all depends on the ionosphere, a high altitude region of the atmosphere, where solar radiation (especially UV light) can ‘ionize’ or knock an electron off, of a nitrogen or oxygen atom. These ‘free electrons’ drastically alter how radio waves go thru this region. There are a...
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 … See more Radio propagation is the behavior of radio waves as they travel, or are propagated, from one point to another in vacuum, or into various parts of the atmosphere.
