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 the speaker A. The frequency of sound waves generated by the loudspeakers is 206 Hz. Let, consider point P among the speakers and long the line joining them, let x be a distance to the right of A on this line. Both speakers emit sound waves that travel directly from the speaker to point P. Determine for what values of x will destructive interference take place?
