two loudspeakers, a and b (the figure (figure 1)), are driven by the same amplifier and emit sinusoidal waves in phase. speaker b is 2.00 m to the right of speaker a. the frequency of the sound waves produced by the loudspeakers is 206 hz. consider point p between the speakers and along the line connecting them, a distance x to the right of speaker a. both speakers emit sound waves that travel directly from the speaker to point p.
