The two loudspeakers, A and B, are driven by the similar amplifier and emit sinusoidal waves in phase. Speaker B is 2 m to the right of speaker A. The frequency of the sound waves generated by the loudspeakers is 206 Hz. Let, consider Point P between the speakers and all along the line joining them, a distance x to the right of speaker A. Both speakers produce sound waves that travel directly from the speaker to point P.
i) Determine the values of x at which destructive interference take place at point P?
ii) Determine the values of x at which constructive interference take place at point P?
