Two loud speakers are 3m apart. A person is listening to a single pitch at 680Hz. The person is along the back wall, which is reasonably far, what are two directions from the center of the speakers where the person would expect to have the music loud? Repeat for two directions that are quiet. The person is now standing at the location that is 4m directly in front of one of the speakers. Determine whether that position is loud, quiet or somewhere between the two extremes. Explain. Use a diagram to help. [Note: Do not assume the person is far away. Comment on why that makes a difference.]

Seiche
A seiche is an oscillating standing wave in a body of water. The term seiche pronounced saysh) can be understood by the sloshing of water back and forth in a swimming pool. The same phenomenon happens on a much larger scale in vast bodies of water including bays and lakes. A seizure can happen in any enclosed or semi-enclosed body of water.
