The prongs of the tuning fork are kept in a vertical plane.

(A) In a resonance column experiment, the tuning fork is held above the open end of the tube. To ensure that the sound waves propagate effectively down the tube, the prongs of the tuning fork are kept in a vertical plane. For a tube closed at one end, the resonance occurs when the length of the air column $L$ satisfies the condition $L + e = (2n - 1) \frac{\lambda}{4}$, where $e$ is the end correction and $n = 1, 2, 3, ...$. The first resonance occurs at $L_1 + e = \frac{\lambda}{4}$ and the second resonance occurs at $L_2 + e = \frac{3\lambda}{4}$. Subtracting these, we get $L_2 - L_1 = \frac{\lambda}{2}$. Thus, the difference between the lengths of the two resonating air columns is equal to half the wavelength of sound in air.

The first overtone frequency of a closed organ pipe is equal to the first overtone frequency of an open organ pipe. Further,the $n^{th}$ harmonic of the closed organ pipe is also equal to the $m^{th}$ harmonic of the open pipe,where $n$ and $m$ are:

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 .... $m$. (Assume the speed of sound in air is $332 \,m/s$)

In a closed organ pipe,the frequency of the fundamental note is $30 \,Hz$. $A$ certain amount of water is now poured into the organ pipe so that the fundamental frequency increases to $110 \,Hz$. If the organ pipe has a cross-sectional area of $2 \,cm^2$,the amount of water poured into the organ tube is . . . . . . $g$. (Take the speed of sound in air as $330 \,m/s$)

In a physics lab,a student is performing an experiment with a resonance tube to find the speed of sound and its end correction. For this,he used a resonance tube of length $120 \ cm$. When the length of the air column in the tube is $16 \ cm$ and $50 \ cm$,he obtains the $I$ and $II$ resonance respectively,while a tuning fork of frequency $500 \ Hz$ is sounded just above the tube. Match the parameters in List-$I$ with their suitable values in List-$II$.

List-$I$ List-$II$

$A$. Wavelength of sound $(cm)$ $p$. $1$

$B$. Height of liquid column at $II$ resonance $(cm)$ $q$. $2$

$C$. Speed of sound $(m/s)$ $r$. $340$

$D$. End correction $(cm)$ $s$. $68$

$E$. Minimum level of liquid column at resonance $(cm)$ $t$. $70$
