Wavenumber -- from Eric Weisstein's World of Physics

Wave Motion Wave Properties


There are unfortunately two different definitions of the wavenumber. French (1971, p. 214) uses the definition


where is the wavelength. However, as French notes, it is more common in theoretical physics to use the definition


which is the convention followed in this work. The term "wavenumber" is sometimes also written out as two separate words (French 1971, p. 214).
