Definition

Let $\phi$ be a harmonic wave expressed as:

$\forall x, t \in \R: \map \phi {x, t} = a \map \cos {\omega \paren {x - c t} }$


The wave number $k$ of $\phi$ is the number of complete wavelengths of $\phi$ per unit distance along the $x$-axis.


Also known as

The term wave number can also be seen as wavenumber.
