22 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 512 Hz produces first resonance when the tube is filled with water 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 256 Hz 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 1 322 ms 1 2 3 335 ms 1 341 ms 4 328 ms 1
