Homework Help: Beat frequency problem

  1. May 1, 2005 #1
    Finally, your friend's twin engine jet airplane lands. As it stands on the runway, you hear the sound of the engines getting louder and softer, rhythmically once every two seconds. The average frequency you hear is 4100 Hz. What is the difference between the individual frequencies of the sounds from each engine and this average?

    f_low-f_ave = ???

    f_high-f_ave = ???
