Diffraction and interference terms
H2 Physics · JC 1 · Medium · Diffraction and interference terms
Two loudspeakers emit sound waves of the same frequency and are driven by the same signal generator. An interference pattern is heard in front of them. Why are the speakers suitable sources for producing a stable interference pattern?
- They are coherent, with a constant phase difference.
- They emit waves of many different frequencies.
- They are very intense compared to background noise.
- They are placed very far apart from each other.
