A person stands directly in front of two speakers that are emitting the same pure tone. The person moves to one side until no sound is heard. At that point, the person is 7 m from one speaker and 7.2 m from the other. What is the frequency of the tone being emitted? Take the speed of sound to be 344 m/s, as usual.
