Consider ten identical sources of sound all giving the same frequency but having phase angles which are random. If the average intensity of each source is I0​ the average of resultant intensity due to all these ten sources will be 4mm and 7mm arrive at a given point with successive phase difference is pie/2.The amplitude [...]
