Root Explanation

Wavelength → It is formed from "wave" (from Old English *wæf*, meaning a moving body of water or undulation) and "length" (from Old English *length*, meaning the measurement of something from end to end). The word "wavelength" refers to the distance between successive crests of a wave, particularly in the context of light or sound waves.

Memory Tip

Think of the 'wave' as a moving undulation and 'length' as the measurement of that wave — together, they describe the distance between wave crests.
