The frequency of a tuning fork is 600 Hz. What is the number of vibrations made by the tunning fork, when the sound produced by the tuning fork travels a distance of 110 ? (Velocity of sound in air is `330 ms^(-1)`)

Explanation

The frequency of tuning fork, (n) = 600 Hz.
In 1 second, it vibrates 600 times.
The distance travelled, (d) = 110 m.
Speed (velocity) of sound, `v = 330 ms^(-1)`.
`therefore` Time taken by sound to travel 110 m is `= ("distance")/("speed")`
`= (110 m)/(330 ms^(-1)) = 1/3 s`
`therefore` Number of vibrations completed by tuning fork in `1//3 s = 1/3 xx 600 = 200` vibrations.
