SUMMARY
The discussion revolves around calculating the points of destructive interference of sound waves emitted by two speakers (S1 and S2) at a frequency of 340Hz, separated by a distance of 3 meters. The correct number of points of destructive interference is established as 3, determined by the condition that the path difference (delta L) must equal n * 0.5 times the wavelength. The wavelength is calculated to be 1 meter, leading to a path difference of 2 meters when the listener is at the final position.
