Answer:
True
Step-by-step explanation:
In destructive interference there is a wave cancellation, either total or partial cancellation, and the resulting wave amplitude is smaller than at least one of the overlapping wave amplitudes. When totally destructive interference occurs, the medium has no effect of the disturbances, the point remaining in equilibrium as long as the overlap lasts. In other words, we can say that destructive interference occurs when the crest of a wave balances or cancels the depression of an interfering wave.
