Final answer:
The amplitude of a wave can be affected by the amplitude of another when the waves overlap, and it is related to the wave's energy but is independent of its speed and frequency. A standing wave is formed by two waves traveling in opposite directions.
Step-by-step explanation:
The statement that the amplitude of one wave is affected by the amplitude of another wave only when they are precisely aligned is true. This effect occurs due to the principle of superposition, where the resultant amplitude at any point is the sum of the amplitudes of individual waves when they overlap. The amplitude of a wave is also directly related to its energy since a wave's energy is proportional to its amplitude squared. However, the amplitude is independent of the wave's speed and frequency.
When discussing a standing wave, it is important to note that it is the superposition of two identical waves that are in phase and propagating in opposite directions, not the same direction as the false statement suggests. Consequently, this statement is false.
