# Thin-wire half wavelength

The half wavelength of a pressure wave in a thin wire.

The thin-wire half wavelength is related to the thin-wire wave speed by —

\begin{align} \label{eq:12901a} \Gamma_{tw} = \frac{c_{tw}}{2 \, f} \end{align}

where —

 $$\Gamma$$ = thin-wire half-wavelength at the specified frequency $$c_{tw}$$ = thin-wire wave speed $$f$$ = frequency
