Long Waves
radio waves with a wavelength of 1 km to 10-20 km. They may propagate because of diffraction of radio waves on the spherical surface of the earth at distances of up to 1,000-2,000 km. Long waves propagate over longer distances through the guide effect of the spherical atmospheric wave guide formed by the surface of the earth and the lower boundary of the ionosphere.
