The required length of the pipe is $1.3~m$

Work Step by Step

We can assume that the speed of sound in air is $343~m/s$. We can find the length of the pipe: $\lambda = \frac{v}{f}$ $2L = \frac{v}{f}$ $L = \frac{v}{2f}$ $L = \frac{343~m/s}{(2)(130.8~Hz)}$ $L = 1.3~m$ The required length of the pipe is $1.3~m$.
