four point source of sound which is isotropic which is located the same on the x-axis. All sources emit sound with the same wavelength the same and the same amplitude, and the same phase. Point P is shown on the x-axis. Suppose that when the sound travels to the point P, the wave does not change (decrease the amplitude is negligible). What is the amplitude of the superposition of the four waves point p if the distance d in the image
