Final answer:
Constructive interference occurs when two waves with the same amplitude and frequency are in phase, resulting in a larger combined amplitude.
Step-by-step explanation:
The statement is true. The amplitude of one wave can indeed be affected by the amplitude of another wave when they are precisely aligned. This phenomenon is known as constructive interference. When two waves with the same amplitude and frequency are in phase (precisely aligned), their amplitudes add up resulting in a larger combined amplitude.
