Interference Flashcards
1
Q
Define coherent sources
A
Two sources oscillating with a constant phase relationship
2
Q
A human hears a loud sound in amongst quieter sounds from two sources - explain why this happens
A
Human hears 2 troughs meet in phase , with a constant phase relationship to produce a constructive maxima
3
Q
How to work out path diff of a minima
A
Path diff = (m+1/2) λ
4
Q
Human produces a quieter sound from two sources- explain this?
A
The meet out of phase , produces a destructive minima
