Final answer:
Constructive and destructive interference are the two types of wave interference.
Step-by-step explanation:
The statement is true. The two types of wave interference are constructive and destructive interference. Constructive interference occurs when two waves combine to increase their amplitude, resulting in a larger overall wave. This happens when the waves are in phase, meaning their peaks and troughs align.
Destructive interference, on the other hand, occurs when two waves combine to decrease their amplitude, resulting in a smaller overall wave or even complete cancellation. This happens when the waves are out of phase, meaning their peaks and troughs do not align.
