The wavelength of the waves arriving at P from two coherent sources S1 and S2 is 4m, while intensity of each wave is Io.The resultant intensity at P is 2Io.Find the minimum value of S2P.

If two sound waves of each intensity I0 gives resultant intensity 2I0 means constructive interference.
For constructive interference the distance should be integral multiple of wavelength. so the minimum 
distance should be equal to wavelength i.e. 4 m
