A Comparison of the Electromagnetic and Acoustic Doppler Effects Using Geometrical Diagrams
Bokor, Nandor
Physics Education, v44 n4 p368-373 Jul 2009
Students often find the difference in the electromagnetic and the acoustic Doppler formulae somewhat puzzling. As is shown below, geometrical diagrams and the concept of "event"--a point in spacetime having coordinates (x,y,z,t)--can be a useful and simple way to explain the physical background behind the fundamental differences between the two kinds of Doppler phenomena. (Contains 4 figures.)
