0A resonance tube is old and has jagged end. It is still used in the laboratory to determine velocity of sound in air. A tuning
\( \mathrm{P} \) fork of frequency \( 512 \mathrm{~Hz} \) produces first resonance when the
W tube is filled with water to a mark \( 11 \mathrm{~cm} \) below a reference mark, near the open end of the tube. The experiment is repeated with another fork of frequency \( 256 \mathrm{~Hz} \) which produces first resonance when water reaches a mark \( 27 \mathrm{~cm} \) below the reference mark. The velocity of sound in air, obtained in the experiment, is close to [JEE (Main) 2019]
(a) \( 322 \mathrm{~ms}^{-1} \)
(b) \( 341 \mathrm{~ms}^{-1} \)
(c) \( 328 \mathrm{~ms}^{-1} \)
(d) \( 335 \mathrm{~ms}^{-1} \)
