Two loudspeakers are placed 3.00 m apart, as shown in the figure (Figure 1). They emit 548 Hz sounds, in phase. A microphone is placed 3.20 m distant from a point midway between the two speakers, where an intensity maximum is recorded. Two loudspeakers are placed 3.00 m apart, as shown in the figure (Figure 1). They emit 548 Hz sounds, in phase. A microphone is placed 3.20 m distant from a point midway between the two speakers, where an intensity maximum is recorded. Two loudspeakers are placed 3.00 m apart, They emit 548 Hz sounds, in phase. A microphone is placed 3.20 m distant from a point midway between the two speakers, where an intensity maximum is recorded.

How far must the microphone be moved to the right to find the first intensity minimum?

Part B

Suppose the speakers are reconnected so that the 548 Hz sounds they emit are exactly out of phase. At what positions are the intensity maximum and minimum now?

How far must the microphone be moved to the right to find the first intensity minimum?
