Use of microwaves and radio waves in communication

WebThese radio waves are used when transmitting between two antennas within line of sight of each other. This means the propagation of the wave is limited to the visual horizon, which is about 64 km on the surface of the Earth, but the waves are large enough to pass through most buildings or foliage unobstructed. WebThe radio waves can penetrate fog, rain, mist, snow, and smoke.. They cannot be confused with infrared energy produced by fire, heated surfaces, warm things, hot gas, or the sun. Radar does not require light to operate, thus it can be used in total darkness as well as intense sunlight without losing efficacy. flights for islamabad

WebHow do radio waves carry information? The basic principle is simple. At one end, a transmitter “encodes” or modulates messages by varying the amplitude or frequency of the wave – a bit like Morse code. At the other, a receiver tuned to the same wavelength picks up the signal and ‘decodes’ it back to the desired form: sounds, images, data, etc. WebRadio waves are used to communicate and send important messages with orders, locations and critical information. During wartime, these transmissions become especially important. Advertisement.
