Resonance Tube

A tuning fork is in unison with an air column of length 20 cm in a resonance tube experiment . If another identical resonance tube, whose length is more by 1 cm than the first tube is used , then 4 beats/second are heard with the same tuning fork. What is the frequency of the tuning fork ?

In the resonance tube experiment , the first resonance is heard when length of air column is l_(1) and second resonance is heard when length of air column is l_(2) . What should be the minimum length of the tube so that third resonance can also be heard.

In resonance tube experiment, first resonance occurs for the length of air - column equal to 25 cm with a tuning fork of frequency 340 Hz. If the length of the air column is decreased by 1cm , the frequency of beats will be

A resonance tube is old and has jagged end. It is still used in the laboratory to determine. Velocity of sound in air. A tuning fork of frequency 512Hz produces first resonance when the tube is filled with wtaer to a mark 11 cm below a reference mark, near the open end of the tube. the experiment is repeated with another fork of frequency 256Hz which produces first resonance when water reaches a mark 27 cm below the reference mark. the velocity of sound in air, obtained in the experiment, is close to :

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.

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 332m//s
