2 Two speakers (labelled 1 and 2) emit a sound at a wavelengthof A = 4m. They produce destructive interference at point P,which is 3 m from speaker 1 and 1 m from speaker 2. What canyou say about the phase constant difference of the twospeakers?13 m21 mO They are completely in phase (Ao = 0)They are completely out of phase (Ago%3DO They have an initial phase phase difference Aog =They have an initial phase phase difference Aon =O More than one of these answers is possible.

In this problem, we will use the path difference and phase difference relation,
