Consider the speaker set-up in the previous question.  Each speaker emits a frequency of 6.6·102 Hz in phase with the other.  The listener is seated directly in front of one speaker, 1.6 m away.  The speakers are 2.4 m away from each other.  How many extra wavelengths are needed for sound to get from speaker 2 to the listener?  Take the speed of sound in air to be 3.4·102 m/s

Consider the speaker set-up in the previous question.  Each speaker emits a frequency of 6.6·102 Hz in phase with the other.  The listener is seated directly in front of one speaker, 1.6 m away.  The speakers are 2.4 m away from each other.  How many extra wavelengths are needed for sound to get from speaker 2 to the listener?  Take the speed of sound in air to be 3.4·102 m/s.

1. Two identical speakers emit sound so that when a wave crest is emitted from one of them, the other
also emits a wave crest. Another way of saying this is that the speakers are in phase with each other.
A person is seated directly in front of one speaker as shown by the blue circle in the figure below.
