Final answer:
The amplitude of a wave, symbolized as A, represents the maximum displacement from the wave's equilibrium position, measured in meters, and plays a role in the wave's energy.
Step-by-step explanation:
The distance above or below the centerline of a waveform represents the amplitude of the wave. This amplitude is conventionally symbolized as A, and it indicates the characteristic height of a wave, measuring how far the wave's medium is displaced from its equilibrium (resting) position.
Wave amplitude can be observed as the height from the equilibrium line to the crest, or from the equilibrium to the trough, and is essential in determining the energy of the wave. The SI unit of amplitude is the metre (m), but other units like centimeters can also be used depending on the context. It is noteworthy that if two waves have the same amplitude, they can still differ in wavelength and frequency.
The distance above or below the centerline of a waveform is known as the amplitude of the wave. The amplitude is a measure of the maximum displacement of the medium from its equilibrium position. It is represented by the symbol A and is measured in units such as centimeters or meters.
