Physics

Two loudspeakers are located 2.53 m apart on an outdoor stage. Alistener is 21.4 m from one and 22.2 m from the other. During thesound check, a signal generator drives the two speakers in phasewith the same amplitude and frequency. The transmitted frequency isswept through the audible range (20 Hz to 20 kHz).(a) What is the lowest frequencyfmin,1 that gives minimum signal (destructiveinterference) at the listener's location? By what number mustfmin,1 be multiplied to get(b) the second lowest frequencyfmin,2 that gives minimum signal and(c) the third lowest frequencyfmin,3 that gives minimum signal?(d) What is the lowest frequencyfmax,1that gives maximum signal (constructiveinterference) at the listener’s location? By what number mustfmax,1 be multiplied to get(e) the second lowest frequencyfmax,2 that gives maximum signal and(f) the third lowest frequencyfmax,3 that gives maximum signal? (Take thespeed of sound to be 343 m/s.)
