False Paradoxes of Superposition in Electric and Acoustic Waves.
Levine, Richard C.
American Journal of Physics, v48 n1 p28-31 Jan 1980
Corrected are several misconceptions concerning the apparently "missing" energy that results when acoustic or electromagnetic waves cancel by destructive interference and the wave impedance reflected to the sources of the wave energy changes so that the input power is reduced. (Author/CS)
