Two identical loudspeakers are located at points and , 2.00 m apart. the loudspeakers are driven by the same amplifier and produce sound waves with a frequency of 784 hz. take the speed of sound in air to be 344 m/s. a small microphone is moved out from point along a line perpendicular to the line connecting and (line in ). (a) at what distances from will there be interference? (b) at what distances from will there be interference? (c) if the frequency is made low enough, there will be no positions along the line at which destructive interference occurs. how low must the frequency be for this to be the case?
