Two loudspeakers, placed on opposite walls of a 10m long room,
emit pure sine waves at f=170 Hz coherently. If we were exactly in
the middle of the room, where the interference of waves is
constructive, what is the shortest distance we should travel
towards one of the speakers so that the waves cancel out
completely?" Assume that the speed of sound at air is 340 m/s.
