In an experiment to measure the speed of sound by a resonating air column, a tuning fork of frequency 500Hz500Hz500Hz 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 50.7cm50.7cm50.7cm and 83.9cm.83.9cm.83.9cm. Which of the following statements is (are) true?
