Two coherent sources of sound, S₁ and S₂, produce sound waves of the same wavelength, λ = 1 m, in phase. S₁ and S₂ are placed 1.5 m apart (see fig.) A listener, located at L, directly in front of S₂ finds that the intensity is at a minimum when he is 2m away from S₂. The listener moves away from S₁, keeping his distance from S₂ fixed. The adjacent maximum of intensity is observed when the listener is at a distance d from S₁. Then, d is:
