WebSkywave is another name for: a. ionospheric wave b. tropospheric wave c. ground wave d. inverted wave a That portion of the radiation which is directly affected by the surface of the earth is called: a. tropospheric wave b. ionospheric wave c. inverted wave d. ground wave d Webas the ground wave mode fades out, a new mode develops: the sky wave. Sky waves are reflections from the ionosphere. While the wave is in the ionosphere, it is strongly bent, or refracted, ultimately back to the ground. From a long distance away this appears as a reflection. Long ranges are possible in this mode also, up to hundreds of miles. WebSky wave definition, a radio wave propagated upward from earth, whether reflected by the ionosphere or not. See more. dish soap for eczema sufferers
