You are an acoustic engineer that wants to cancel out reflections of sound with a frequency of f=170 Hz between rows of successive concert hall seats. You also need at least one meter between the seats to fit the people in. Show that the minimum distance should you would put between the rows is L=1.5 m. Assume the speed of sound is vs = 340 m/s.
