Two speakers (labelled 1 and 2) emit a sound at a wavelength of A = 4 m. They produce destructive interference at point P, which is 3 m from speaker 1 and 1 m from speaker 2. What can you say about the phase constant difference of the two speakers? 1 3 m 2 P 1 m O They are completely in phase (Aoo = 0) They are completely out of phase (Ap = 7) %3D O They have an initial phase phase difference Ago = O They have an initial phase phase difference Ago = O More than one of these answers is possible.
