Physics - Sound Wave Question with Solution | TestHub

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