9PRACTICE PROBLEM
A radio with two detached speakers is tuned to a radio station playing an alert tone at 1050 Hz. The speakers are initially placed at the same point, 3.20 m away from a listener. One speaker is moved backward from the listener. What distance x between the two speakers will create destructive interference for the second time at the listener's position?
