Two organ pipes, one open and one closed at one end, resonate at their first overtones with frequencies 600 Hz and 750 Hz respectively. If the speed of sound is 330 m/s, the ratio of the lengths of the pipes is:

Two closed organ pipe A and pipe B have the same length. A is wider than B. they resonate in the fundamental mode at frequencies ${v_A}\,\,and\,\,{v_B}$ respectively, then

The second overtone of an open organ pipe has the same frequency as the first overtone of a closed pipe $L$ meter long. The length of the open pipe will be

Speed of sound at constant temperature depends on

A closed organ pipe is vibrating in first overtone and is in resonance with another open organ pipe vibrating third harmonic the ratio of lengths of the pipes respectively is

Two closed organ pipes $A$ and $B$, have the same length. $A$ is wider than $B$. They resonate in the fundamental mode at frequencies ${n_A}$ and ${n_B}$ respectively, then

If the temperature is raised by $1{\rm{ }}K$ from $300{\rm{ }}K$ the percentage change in the speed of sound in the gaseous mixture is $\left( {R = 8.31{\rm{ }}J/mol - K} \right)$

A whistle revolves in a circle with an angular speed of $20\,\,rad/\sec$ using a string of length $50\,\,cm$. If the frequency of sound from the whistle is $385\,\,Hz$, then what is the minimum frequency heard by an observer, which is far away from the centre in the same plane? $\left( {v = 340\,\,m/s} \right)$

If the temperature is raised by $1{\rm{ }}K$ from $300{\rm{ }}K$ the percentage change in the speed of sound in the gaseous mixture is $\left( {R = 8.31{\rm{ }}J/mol - K} \right)$

A resonance pipe is open at both ends and $30\,\,cm$ of its length is in resonance with an external frequency $1.1\,\,kHz$. If the speed of sound is $330\,\,m/s$, which harmonic is in resonance?

If the speed of sound in air is $340$ m/s at $20^{\circ}C$, and a tuning fork of frequency $440$ Hz produces resonance at consecutive lengths of $18.75$ cm and $56.25$ cm in a resonance tube, is the experiment being conducted at $20^{\circ}C$? Explain your reasoning.
