Speakers A and B are emitting sound wave in phase with the same wavelength 175 Hz. Speaker A is a distance 2.00 m to the left of speaker B and point P is 3.50 m to the right of B, so 5.50 m to the right of speaker A. The speed of sound in the air is 350 m/s. Is the interference at point P constructive or destructive?
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.
