"In a resonance column experiment, when the length of the air column is increased by changing the water level sound heard becomes louder." Why?

The glass tube of a resonance tube apparatus is held vertically and the length of the air column in it can be adjusted by adjusting the water level in the tube using a pipe and funnel arrangement. A tuning fork, of frequency v is sounded above the air column in the tube while the length of the air column is slowly increased, starting with a small value. whenever resonance occurs, it is indicated by a loud sound. the two successive lengths at which resonance occurs are l_(1) and l_(2) . find the speed of sound in air and the end correction for this pipe.

In the resonance column experiment, why do we use water ? Can we use any other liquid ?

In an experiment to measure the speed of sound by a resonating air column, a tuning fork of frequency 500 Hz is used. The length of the air column is varied by changing the leavel of water in the resonance tube. Two successive resonances are heard at air columns of length 50.7 cm and 83.9 cm. Which of the following statements is (are) true?

A student performed the experiment to measure the speed of sound in air using resonance air-column method. Two resonances in the air-column were obtained by lowering the water level. The resonance with the shorter air-column is the first resonance and that with the longer air-column is the second resonance. Then,

A student performed the experiment to measure the speed of sound in air using resonance air-column method. Two resonances in the air-column were obtained by lowering the water level. The resonance with the shorter air-column is the first resonance and that with the longer air-column is the second resonance. Then, A. the intensity of the sound heard at the first resonance was more than at the second resonance B. the prongs of the tuning fork were kept in a horizontal plane above the resonance tube C. the ampitude of vibration of the end of the prongs is typically around 1 cm D. the length of the air-column at the first resonance was somewhat than 1//4 th of the wavelength of the sound in air.

In the experiment for the determination of the speed of sound in air using the resonance column method, the length of the air column that resonates in the fundamental mode, with a tuning fork is 0.1m . When this length is changed to 0.35m , the same tuning fork resonates with the first overtone. Calculate the end correction.
