A tuning fork of frequency 480 Hz is used in an experiment of measuring speed of sound (v) in air by resonance tube method. Resonance is observed to occur at two successive lengths of the air column, `l_(1)=30cm` and `l_(2)=70cm`. Then, v is equal to:

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