The frequency of a tuning fork is 256 Hz . The velocity of sound in air is 344 ms-1  . The distance travelled (in meters) by the sound during the time in which the tuning fork completes 32  vibrations is :

Given frequency of turning fork =256 Hz Velocity of sound in air v=344 m/s Time taken to complete one vibrationT=1F=1256 Total time for 32 vibrations t=32T Distance travelled by sound S=vt S=344×32T  = 344×32256 =43 cm
