Two loudspeakers are placed 3.00meters apart, as shown in thefigure . They emit 494 Hz sounds, in phase. A microphoneis placed 3.20 meters distant from a point midway between the twospeakers, where an intensity maximum is recorded.

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