Two coherent sources of a sound S₁ and S₂ produce sound waves of the same wavelength $\lambda =1m$ in the phase. S₁ and S₂ are placed 1.5m apart. A listener located at L, directly in front of S₂ find that the intensity is at a min. When hs is 2m away from S₂. The listener moves away from S₁ keeping his distance from S₂ fixed. The adjacent maxmimum of intensity is observed when the listener is at a disatnce d from S₁. Then d is:
