Being two pure wave loudspeakers, which are on opposite walls of a 10m long room, in a form of length f = 170 Hz in a coherent way. If we were exactly in the middle of the room, where wave interference is constructive, what is the shortest distance we must move towards one of the speakers for the waves to cancel out completely? Suppose the speed of sound is not 340 m/s.
Interference of sound
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.
