1 Two sound waves emerging from a source reach a point simultaneously along two path of propagation when the path difference 55 cm the resultant intensity is zero at that point As the path difference gradually increases we get zero intensity next time when path difference is 77 cm If the speed of the sound of the sound is 330 m sec the frequency of the source is 1 500 Hz 3 1500 Hz 2 4 1000 Hz 2000 Hz
