9. Two small stereo speakers are driven in step by the same variable- frequency oscillator. Their sound is picked up by a microphone arranged as shown in the figure. For what two lowest frequencies above 100 Hz does their sound at the speakers produce (a) constructive interference and (b) destructive interference? (Given sound speed = 345 m/s.) 2.00 m 4.50 m Microphone
