Waves question

2019 · 12 Jan · Shift 2 · Q52

JEE MainPhysicsWavesMCQ+4 / −1
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. A
    335 ms–1
  2. B
    328 ms–1
  3. C
    341 ms–1
  4. D
    322 ms–1
