Слайд 6


How apply radio waves radio waves are emitted via an antenna the transmission of long-wave broadcasting stations can be taken at a distance of several thousand kilometers medium wave stations are audible within a thousand kilometers. The energy of the short waves dramatically decreases as the distance from the transmitter. study of short and ultrashort waves showed that they quickly disappear when you go near the Ground. When the direction radiation upward short wave back
