Definitions:

Wavelength

Wavelength refers to the distance between successive peaks (or troughs) of a wave, especially in physics, indicating the physical property of a wave that influences color and pitch in light and sound waves, respectively.

Amplitude

The extent of a vibratory movement measured from the mean position to an extreme, commonly used in the context of waves to denote the height of a wave peak.

Wavelength

The distance between consecutive crests of a wave, especially points in a sound wave or electromagnetic wave, which determines its characteristics like color or pitch.

Amplitude

The magnitude of change in a periodic variable, such as a wave, from its baseline or equilibrium position.
