Which of the following describes wavelength?

Wavelength is defined as the distance between two corresponding points on consecutive waves, such as from crest to crest or trough to trough. This distance is crucial in determining various wave properties, such as frequency and speed, and is a fundamental characteristic in the study of waves across different mediums.

In contrast, the height of a wave, referred to as amplitude, measures the maximum displacement of points on a wave from its rest position, while wave speed indicates how quickly the wave propagates through space. The energy carried by a wave relates to its amplitude and frequency but does not define the physical distance between points on the wave. Thus, identifying wavelength correctly helps in understanding the broader aspects of wave behavior in physics.
