Final answer:
The statement is false because the amplitude of one wave can indeed be affected by the amplitude of another even if they are not perfectly aligned, due to the principle of superposition.
Step-by-step explanation:
The statement is false. The amplitude of one wave is not solely affected by the amplitude of another wave being precisely aligned with it. In physics, particularly in wave theory, we discuss the principle of superposition. This principle states that when two or more waves meet at a point, the total amplitude at that point is the sum of the amplitudes of the individual waves. This means that waves can affect each other's amplitudes even if they are not perfectly aligned, and interference patterns can occur.
For instance, if two waves of equal frequency and amplitude are in phase (i.e., crest aligns with crest and trough aligns with trough), they will constructively interfere with each other, resulting in a wave with greater amplitude. Conversely, if they are out of phase (i.e., the crest of one aligns with the trough of another), they will destructively interfere, possibly resulting in a wave of reduced or even zero amplitude.
