Web13 okt. 2015 · To do this with radiowaves, you'd need to build passive devices that are powered by radio waves alone, and retransmit new waves at different frequencies. This can be done, but requires high power radar, and its large. Light does this with matter itself. 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.

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.
