4. You are standing 4.0 m in front of a speaker, which is 3.0 m away from the other speaker on a line perpendicular to your line with the first speaker (see diagram below). They are playing a 688 Hz sinusoidal tone in phase. Assume the speed of sound is 344 m/s. Are you at a node, an antinode or some other point? Show a calculation that proves your point (hint: is a node a point of constructive or destructive interference?).
