A sound of intensity 27 lo is produced at the end A It travels down to the point B along three different paths I II and III as shown in the figure Path II is semi circular At B no sound is heard a Find the maximum possible wavelength of sound b Find the minimum value of x for above wavelength c Find the equations of the three waves arriving at B Assume that sound energy is equally distributed among the three paths The path length III is more than that of II The amplitude of wave corresponding to intensity lo is A The wave velocity is v A 1 0m B
