These are waves that can pass through vacuum in addition to passing through matter. In other words, a material medium is not necessary for their propagation. They consist of periodic variations of electric and magnetic fields at right angles to each other and also at right angles to the ..

Radio waves are electromagnetic waves of wavelength 10 - 3 m and higher. Their frequency range is from a few kHz to nearly a few hundred MHz. The propagation of radio waves through the atmosphere is relevant in all modern forms of communication: ..

An electromagnetic wave is a disturbance, which does not require any material medium for its propagation and can travel even through vacuum. They are caused due to varying electric and magnetic fields. Radio waves and light waves are examples for electromag..

The radio horizon for space waves is about four-thirds as far as the optical horizon. This beneficial effect is caused by the varying density of the atmosphere, and because of diffraction around the curvature of the Earth. The radio horizon of an antenna is given, with..

(the portion of the atmosphere closest to the ground). Frequencies below the HF range travel around the curvature of the Earth, sometimes right around the globe. These ground waves, or surface waves as they are called, are one of the two original means of beyond- the- horizon pr..
