Answer: The correct answer is constructive interference.
Step-by-step explanation:
Interference is the phenomenon in which there is superposition of the two waves. Interference are of two types: Constructive interference and Destructive interference.
Constructive interference occurs when the there is a superposition of the two waves. The resulting wave has a large amplitude.
Destructive interference occurs when the there is a superposition of the two waves. The resulting wave has a low amplitude.
Therefore, Constructive interference occurs when two waves overlap and the resulting wave has a larger amplitude.
