"In radio communication, skywave or skip refers to the propagation of radio waves reflected or refracted back toward Earth from the ionosphere, an electrically charged layer of the upper atmosphere. Since it is not limited by the curvature of the Earth, skywave propagation can be used to communicate beyond the horizon, at intercontinental distances. It is mostly used in the shortwave frequ… " - Can radio waves be reflected

WebApr 30, 2024 · Radio waves can be reflected and refracted in a manner similar to light. They are affected by the ground terrain, atmosphere and other objects. Maxwell’s equations state that a time varying magnetic field produces an electric field and a time varying electric field produces a magnetic field. This is kind of a chicken and egg situation. WebHigher frequency waves are able to pass through the atmosphere entirely and reach the ground. This process also works in reverse for radio waves produced on the earth. The high frequency waves pass through the ionosphere and escape into space while the low frequency waves reflect off the ionosphere and essentially "skip" around the earth.

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. WebRadio waves produced on Earth are mostly manmade and are often at one specific frequency. In fact, this is one way astronomers can tell a signal created on Earth apart …

WebHowever, not all radio waves are refracted by the ionosphere, wavelengths smaller than 10 meters and below – corresponding to frequencies of 30 MHz and above – tend to pass through the ionosphere. Ionisation is the process in which atoms gain or lose electrons.
