Total: 54

In an experiment to measure the speed of sound by a resonating air column, a tuning fork of frequency 500Hz is used. The length of the air column is varied by changing the level of water in the resonance tube. Two successive resonances are heard at air columns of length 50.7cm and 83.9 cm. Which of the following statements is (are) true?

The speed of sound determined from this experiment is 332m/s
The end correction in this experiment is 0.9cm
The wavelength of the sound wave is 66.4cm
The resonance at 50.7cm corresponds to the fundamental harmonic
