If a tuning fork of frequency ( f_(0) ) 340 Hz and tolerance pm1% is used in the resonance column method for determining the speed of sound. If the first and the second resonance are measured at l_(1) = 24.0 cm and l_(2) = 74.70 cm , then the permissible error in speed of sound is
A standing tuning fork of frequency f is used to find the velocity of sound in air by resonance column appartus. The difference two resonating lengths is 1.0 m . Then the velocity of sound in air is
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?
A tuning fork of frequency n is held near the open end of tube, the tube is adjusted until resonance occurs. If the two shortest lengths to produce resonance are L_1 and L_2 , then the speed of the sound is
