The wavelength of sound waves arriving at P from two coherent sources S_1 and S_2 is 4 m as shown. While intensity of each wave is I_0 the resultant intensity at point P is 2I_0 find minimum value of x

Assertion Two coherent sources transmit waves of equal intensity I_(0) Resultant intensity at a point where path difference is lambda/3 is also I_(0) . Reason In interference resultant intensity at any point is the average intensity of two individual intensities.

Figure shows two line sources of sound, S_1 and S_2 separated by a distance 4 m.The two sources are in same phase at all times.The source emit same power and their lengths are also same.A detector moves along a circle with center at S_2 and radius 3m. The wavelength of the sound is 1m.When it is at A the intensity of sound due to source S_2 only is I_0 . The intensity of sound at B due to S_1 only is :
