1. Two identical loudspeakers are driven by the same oscillator at frequency 480 Hz. They are located on the ground a distance of 4.0 m from each other. Starting far from the speakers, a man walks straight toward the right-hand speaker as shown. How many maxima does the man walk through and at what distances from the speaker are the maxima? Speaker 1 Speaker 2 Observer
