In a resonance column first and second resonance are obtained at depths $22.7\,\,cm\,\,and\,\,70.2\,\,cm$. The third resonance will be obtained at a depth

A resonance air column of length $20\,\,cm$ resonated with a tuning fork of frequency $250\,\,Hz$. The speed of sound in air is

An air column in a pipe, which is closed at one end, will be in resonance with a vibrating body of frequency $166\,\,Hz$, if the length of the air column is

If $v$ is the speed of sound in air then the shortest length of the closed pipe which resonates to a frequency $v$, is

If in an experiment for determination of velocity of sound by resonance tube method using a tuning fork of $512\,\,Hz$, first resonance was observed at $30.7\,\,cm$ and second was obtained at $63.2\,\,cm$, then maximum possible error in velocity of sound is (consider actual speed of sound in air is 3$332\,\,m/s$

Air is blown at the mouth of a tube of length $25\,\,cm$ and diameter equal to $2\,\,cm$ open at both ends. If velocity of sound in air in $330{\mkern 1mu} \,\,{\mkern 1mu} {\rm{m}}{{\rm{s}}^{ - 1}}$, the sound emitted will have all the frequency in the group
