Question
What is the interference of sound waves?
Advertisements
Solution
If two longitudinal (sound) waves arrive at a point such that compression of one wave coincides with the compression of the other wave and rarefaction coincides with the rarefaction of the other wave and then the resultant amplitude of a wave is maximum or if compression of one wave falls on the rarefaction of the other wave and vice versa and then the amplitude of the resulting wave is minimum, then these effects are interference of longitudinal (sound) waves.
