Ultra long wave
Web16 Apr 2024 · Generally, ultra-long wave, long wave, and medium wave radio communications utilize ground wave propagation. 2. Sky wave propagation . Sky wave refers to the radio wave that is radiated by the antenna to the high altitude and returned to the ground after being reflected or refracted by the sky ionosphere. The propagation route is … WebHowever, electromagnetic waves have been observed with incredibly long wavelengths -- these waves are known as ultra low frequency (ULF) waves, or micropulsations. Since frequency and wavelength are inversely proportional ( v = fλ , for electromagnetic waves c = fλ ), the name "ultra low frequency"is equivalent to "ultra long wavelength" -- although …
