Question: sound source A is located at x = 0 y = 0 and sound source B is located at x = 0 and y =

sound source A is located at x=0 y=0 and sound source B is located at x=0 and y=1.5m the two sources radiate coherently and in phase an observer at x=13m y=0 notes that as he takes a few steps from y=0 in either the +y or -y direction the sound intensity diminish. What is the lowest frequency f1 of the sources that can account for that observation and what is the second lowest frequency f2 of the sources that can account for that observation? give answers in kHz
