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… WebJan 24, 2024 · On Earth, with atmosphere and trees and buildings and so on, different wavelengths/frequencies will be reflected and absorbed differently.

WebMay 6, 2024 · For metals, whether an electromagnetic (EM) wave is reflected or absorbed is determined primarily by (1) the frequency (or wavelength) of the incident wave, and (2) the density of electrons in the material. WebAug 7, 2024 · Radio waves are the perfect form of electromagnetic radiation for detecting reflections. When light bounces off a distant object, it's already very faint, and it becomes fainter as it returns....

If the elapsed time between the arrivals of the two … 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.
