Which phenomenon results from the superposition of waves causing the overall wave to increase in amplitude?

Explanation:
When waves meet, they superpose by adding their displacements at every point. If their crests align with crests and troughs align with troughs, the amplitudes add up, producing a larger overall wave. This increase in amplitude is a hallmark of constructive interference, a specific outcome within the broader phenomenon of interference. So the situation described—waves combining to yield a bigger amplitude—maps directly to interference. The other terms refer to different acoustic effects: noise is a random mix of waves, an echo is a delayed reflection, and reverberation comes from multiple reflections that keep the sound going.
