Question

the frequency of a fork is 500hz velocity of sound is 350 m/s the distance through which sound travel by the time the fork makes 125 vibrations is

Answer 1

HERE IS YOUR ANSWER_
******
Given:
Frequency =  500 Hz
Speed = 350 m/s

Hence
No of oscillations per unit second = 500
Time taken per oscillation = 1500s
Time take for 125 oscillations = 125500=14s
Thus
The distance travelled by the wave in 14s is
14×350=87.5 m
