Final answer:
The statement is false.
Step-by-step explanation:
The amplitude of one wave can be affected by the amplitude of another wave even when they are not precisely aligned. This phenomenon is called interference. Interference occurs when two or more waves combine and their amplitudes add up or cancel out, resulting in constructive or destructive interference.
An example of constructive interference is when two waves with the same amplitude and frequency are perfectly aligned, resulting in a wave with double the amplitude. An example of destructive interference is when two waves with the same amplitude and frequency are precisely out of phase, resulting in complete cancellation of the wave.
Therefore, the amplitude of one wave can be affected by the amplitude of another wave even when they are not precisely aligned.
