What term describes the height of a wave?

• A. Frequency
• B. Amplitude
• C. Wavelength
• D. Crest

Answer: (B)

The height of a wave is described by the term amplitude. Amplitude refers to the maximum distance the wave reaches from its equilibrium position, which is typically the baseline level of the wave. In the context of a wave, whether it be sound, light, or water waves, amplitude indicates the strength or intensity of the wave. It is directly related to the energy carried by the wave; higher amplitude signifies more energy and thus a more intense wave. In contrast, frequency pertains to how often the wave oscillates or cycles in a given time, usually measured in hertz. Wavelength is the distance between successive crests or troughs of the wave. The crest is the highest point of the wave, but it is the amplitude that measures how far this crest is from the equilibrium position. Therefore, amplitude is the precise term to describe the height of the wave.
