There are two speakers on the x-axis and they are positioned such that one is behind the other. Both speakers emit a wave with the same frequency and amplitude, along the x-axis, which we denote as f and a. The sound intensity is maximum, with amplitude 2a, when speaker 2 is 10 cm behind speaker 1. The intensity decreases as speaker 2 is moved forward and first reaches a minimum when it is
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.
There are two speakers on the x-axis and they are positioned such that one is behind
the other. Both speakers emit a wave with the same frequency and amplitude, along
the x-axis, which we denote as f and a. The sound intensity is maximum, with
amplitude 2a, when speaker 2 is 10 cm behind speaker 1. The intensity decreases as
speaker 2 is moved forward and first reaches a minimum when it is 20 cm in front of
speaker 1. What is:
1. The phase difference between the two loudspeakers?
2. The amplitude of the sound (as a multiple of a) if the speakers overlap?
