\frac{l_{2}+e}{l_{1}+e}= \frac{3\lambda /4}{\lambda /4}= 3

e= \frac{l_{2}-3l_{1}}{2}= \frac{70.2-3\times 22.7}{2}

e= 1.05cm

 

Fundamental frequency with end correction -

\nu _{0}= \frac{V}{4\left ( l+e \right )}     (one end open)

\nu _{0}= \frac{V}{2\left ( l+2e \right )}    (Both end open)

e = end correction
