Which term describes how fast a wave travels in a given distance?

The term that describes how fast a wave travels in a given distance is speed. In the context of waves, speed is defined as the distance that a wave travels over a unit of time. This relationship is crucial in various applications, including physics and engineering, as it indicates how quickly a wave propagates through a medium.

Understanding wave speed involves recognizing that it depends on both the type of wave and the medium through which it is traveling. For example, sound waves travel at different speeds in air and water, while light travels at a different speed in a vacuum compared to other materials.

Amplitude refers to the height of the wave from its rest position which indicates the energy of the wave but does not provide information about the rate at which it travels. Frequency refers to the number of wave cycles that pass a point in one second, while wavelength describes the distance between successive crests or troughs of the wave. While all these terms are important concepts in wave mechanics, speed specifically quantifies how quickly the wave moves through space.
