A closed organ pipe has a fundamental frequency of $f$. If the temperature increases, which of the following is true about the fundamental frequency and speed of sound?

If the length of a closed organ pipe is doubled, its fundamental frequency will be:

A hollow pipe of length $0.8\,\,m$ is closed a one end. At its open end a $0.5\,\,m$ long uniform string is vibrating in its second harmonic and it resonates with the fundamental frequency of the pipe. If the tension in the wire is $50\,\,N$ and the speed of sound $320\,\,m{s^{ - 1}}$, the mass of the string is

The stationary wave $y = 2a\,\,\sin \,\,\,k\,\,x\,\,\cos \,\,\,\omega t$ in a closed organ pipe is the result of the superposition of $y = a\,\,\,\,\sin \left( {\omega t - kx} \right)$ and

In $1{\rm{ }}m$ long open pipe what is the harmonic of resonance obtain with a tuning fork of frequency $480\,\,Hz$?

A pipe $30\,\,cm$ long is open at both ends. Which harmonic mode of the pipe is resonantly excited by a $1.1\,\,\,kHz$ source? (Take speed of sound in air $= 330\,\,m{s^{ - 1}}$

In the experiment to determine the speed of sound using a resonance column

A pipe closed at one end and open at the other end, resonate with sound waves of frequency $135\,\,Hz$ and also $165\,\,Hz$, But not with any wave of frequency intermediate between these two. Then the frequency of the fundamental note is

An organ pipe, open from both end produces $5$ beats per second when vibrated with a source of frequency $200\,\,Hz$. The second harmonic of the same pipes produces $10$ beats per second with a source of frequency $420\,\,Hz$. The frequency of source is

The frequency of fundamental note in an organ pipe is $240\,\,Hz$. On blowing air, frequencies $720\,\,Hz$ and $1200\,\,Hz$ are heard. This indicates that organ pipe is

Two closed organ pipes of lengths $L_1$ and $L_2$ ($L_1 < L_2$) produce 2 beats/s when sounded together. If $L_2$ is slightly increased, the beat frequency increases. The fundamental frequencies $f_1$ and $f_2$ are related by:
