\frac{7 \lambda}{3}=\frac{40}{1} \\

7 \lambda=120 \\

\lambda=\frac{120}{7} \\

& V=n \lambda                                   n=200 \mathrm{~Hz} \\                                                                               V=\frac{200 \times 120}{7}

V=3428.58 \mathrm{~cm} \\

or V=34.29 \mathrm{~m}
