Which type of interference results in constructive interference?

Constructive interference occurs when two or more waves combine to produce a wave with a larger displacement. This happens when the crest of one wave overlaps with the crest of another wave, resulting in an increase in the amplitude of the wave. The same applies when the troughs overlap. This type of interference is often associated with the phenomenon of resonance.
