Interference from Different Path Lengths

Interference from different path lengths explains how two sound sources can create changing patterns in space. The sources may or may not start in phase, but they emit waves at the same frequency. When they are in phase, they are called coherent sources, and that is easy to arrange by feeding both speakers from the same sour...

Imagine dos altavoces alimentados por la misma fuente de sonido de una sola frecuencia. En este caso, las dos ondas no tienen diferencia de fase en los altavoces.

Recordemos que las ondas sonoras son ondas viajeras que involucran coordenadas espaciales y temporales. Entonces, en un punto P, la distancia recorrida por las dos onda...
