Longitudinal wave problem (tunning fork)

posted by .

I have this for a physics question

A 320 hz tuning fork vibrates for 8s. During this time each tine of the fork travels a total distance of 10.3 cm.

first I multiplied 320 by 8.( 2 560)
then i divided 10.3 by 2 560. then i divided that answer by 4 since there are four amplitudes (ei the tine moves up then down, then below again, then up to its original position.

My final answer was 0.001005859 cm

could u tell me if i am correct


  • Longitudinal wave problem (tunning fork) -

    Are you supposed to find the amplitude of vibration? If so, you did it correctly.
