Suppose that two waves traveling in the same direction and with the same amplitude on a rope are interfered with. Let the amplitude of each wave be 9.8 mm and the phase difference of the two waves be 100 °. a) What is the amplitude of the total interfering wave and give information about the type of interference. b) What phase difference does two waves produce a total wave of 4.9 mm in amplitude ?
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.
