What does waviness mean?
Waviness is the noun for the quality or condition of being wavy. It usually describes a surface, line, fabric, or strand that rises and falls in gentle curves, as in a slight waviness in a sheet of glass or the natural waviness of long hair. It can also describe movement or sound that is unsteady or wavering, particularly in a voice. The word is neutral and relatively formal, and it may carry either a positive connotation, suggesting softness and movement, or a negative one, indicating an unwanted irregularity in something intended to be flat or straight. “Waviness” is normally used in the singular as an abstract noun, although plural forms occur in formal or technical writing. It is a useful term when the emphasis is not on the wavy shape itself but on the quality of being undulating or uneven.
