Is the interference along the x -axis maximum constructive interference, perfect

Question

Is the interference along the x-axis maximum constructive interference, perfect destructive interference, or something in between? Assume Vsound = 340 m/s

a. The interference along x-axis is maximum constructive interference.

b. The interference along x-axis is perfect destructive interference.

c. The interference along x-axis is something between maximum constructive interference and perfect destructive interference.

Two loudspeakers emit sound waves along the x-axis. Speaker 2 is 2.0 m behind speaker 1. Both loudspeakers are connected to the same signal generator, which is oscillating at 340 Hz , but the wire to speaker 1 passes through a box that delays the signal by 1.47 ms. Is the interference along the x-axis maximum constructive interference, perfect destructive interference, or something in between? Assume Vsound = 340 m/s The interference along x-axis is maximum constructive interference. The interference along x-axis is perfect destructive interference. The interference along x-axis is something between maximum constructive interference and perfect destructive interference.

Explanation / Answer

The path is perfect deconstructive interference. It is NOT constructive or somewhere inbetween.
