Long Waves

   Also found in: Dictionary/thesaurus, Financial, Wikipedia 0.01 sec.
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.

The sky was clear, the sun midway down the western sky; long waves, capped by the breeze with froth, were running with us.
The sea--the great, the glorious sea, that dashed its long waves against the coast--was stretched out before him.
The whole earth seethed, and sky and sea: and the long waves raged along the beaches round and about, at the rush of the deathless gods: and there arose an endless shaking.
