Do radio waves travel around the Earth or through it?

Web1 mrt. 2011 · HF is different. Strictly speaking, HF radio covers the band from 3 to 30 MHz. At these frequencies, vertically polarized waves travel great distances over land and even greater distances over sea water. But the real advantage of HF is skywave propagation, where a single link can span distances as great as 3,000 km (a little less than 1,900 miles). WebRadio waves were first predicted by the theory of electromagnetism proposed in 1867 by Scottish mathematical physicist James Clerk Maxwell. His mathematical theory, now called Maxwell's equations, predicted that a coupled electric and magnetic field could travel through space as an "electromagnetic wave".Maxwell proposed that light consisted of … Web13 jan. 2024 · Radio waves naturally travel in straight lines, which means you would naturally expect (due to the curvature of the world) that no radio station would transmit farther than 30 or 40 miles.
