JEE Main 2022 Physics question
In an experiment to determine the velocity of sound in air at room temperature using a resonance tube, the first resonance is observed when the air column has a length of 20.0 cm for a tuning fork of frequency 400 Hz is used. The velocity of the sound at room temperature is 336 . The third resonance is observed when the air column has a length of cm.
Answer: 104
Solution
For a closed tube at the first resonance and at the third. The wavelength is = v/f = 336/400 = 0.84
