Sky waves: a radio wave that is reflected back to earth by the ionosphere or a communications satellite; permits transmission around the curve of the earth’s surface Line of propagation: is the electro-magnetic radiation or acoustic wave propagation. Electromagnetic transmission light travels in a straight line. The rays or waves can be diffracted‚ refracted‚ reflected‚ or absorbed by atmosphere and obstructions with material and generally cannot travel over the horizon or behind

    Doppler effect The Doppler effect‚ named after Christian Doppler‚ is the change in frequency and wavelength of a wave as perceived by an observer moving relative to the source of the waves. For waves that propagate in a wave medium‚ such as sound waves‚ the velocity of the observer and of the source are relative to the medium in which the waves are transmitted. The total Doppler effect may therefore result from motion of the source‚ motion of the observer‚ or motion of the medium. Each of these

    apparent bending of waves around small obstacles and the spreading out of waves past small openings. Similar effects occur when a light wave travels through a medium with a varying refractive index‚ or a sound wave travels through one with varying acoustic impedance. Diffraction occurs with all waves‚ including sound waves‚ water waves‚ and electromagnetic waves such as visible light‚ X-rays and radio waves. As physical objects have wave-like properties (at the atomic level)‚ diffraction also occurs
