3 A tuning fork with frequency 800 Hz produces resonance in a resonance column tube with upper end open and lower end closed by water surface Successive resonance are observed at length 9 75 cm 31 25 cm and 52 75 cm The speed of sound in air is a 500 m s b 156 m s c 344 m s d 172 m s Odisha NEET 2019 4 A tuning fork is used to produce resonance in a glass tube The length of the air column in this tube can be adjusted by a variable piston At room temperature of 27 C two successive resonances are produced at 20 cm and 73 cm of column length If the frequency of the tuning fork is 320 Hz the velocity of sound in air at 27 C is a 330 m s c 350 m s b 339 m s d 300 m s NEET 2018
