“…The following paragraphs summarize the salient features of the life and times of the person whose name is coupled inextricably with the above-mentioned phenomena: Christian Andreas Doppler. Unabashed reference is made to an excellent text published in 1992 by Springer-Verlag: The Search for Christian Doppler, by Alec Eden (Eden 1992). Dr. Eden, incidentally, is a surgeon who makes use of the Doppler principle in his work in transcranial Doppler sonography.…”

“…If a sound wave source and an observer (who hears the sound) have a relative motion, then the frequency which is observed by the observer depends on the direction of the source's motion and therefore it defers from the original frequency. Using the Doppler Effect formulation [2][3][4][5][6][7][8][9], one can justify the relation between the observed and emitted frequencies. In this paper, we investigate the Doppler effect, in three general categories; first, when the observer and the source are located on a reference frame and are alone a straight line, second, when they are on different reference frames having relative motions, and third, when they are not located along a straight line; their velocities make an angle with the direction of sound emission.…”

The Austrian Wuhan Doppler (1803-1853) revealed in a paper in 1842 [1] that the color of a luminous substance should change due to its relative movement and observer's. This effect which is named Doppler Effect can be seen through all the waves, and Doppler himself impressed on its application in acoustic waves. In 1845 an empirical experiment was performed using a moving truck carrying few people blowing trumpets. In this paper, the Doppler Effect has been investigated for moving observer, source, and media while they are moving in a straight line with together, and moving with an angle between the sound wave and observer's moving direction.

“…In Newtonian mechanics, the law of conservation of momentum can be derived from the law of action and reaction, which states that every force has a reciprocating equal and opposite force. Under some circumstances one moving charged particle can exert a force on another without any return force [1][2][3][4][5][6]. Moreover, Maxwell's equations, the foundation of classical electrodynamics, are Lorentzinvariant.…”
