A tube closed at one end containing air produces when excited the fundamental note of frequency $512 ext{ Hz}$. If the tube is open at both ends, the fundamental frequency that can be excited is (in Hz)

Question

A tube closed at one end containing air produces when excited the fundamental note of frequency $512	ext{ Hz}$. If the tube is open at both ends, the fundamental frequency that can be excited is (in Hz)

Aicharya · Accepted Answer

Fundamental frequency of closed pipe is $\frac{v}{4l}$ and that of open pipe is $\frac{v}{2l}$ which is two times that of the closed pipe. i.e. $1024	ext{ Hz}$.
