A source of wave vibrates with a frequency 500 Hz. The wave travels 33m in `0.1`s . How far does the waves travels when the source executes 150 vibrations ?

Explanation

The frequency of the tuning fork = 500 Hz . The time taken for one wave to pass - `(1)/(500)` s
`therefore` Therefore the time taken for 150 vibrations (waves )
`= (1)/(500) xx 150 = 0.3`s
Hence the distance travelled by sound in 0.3 s is
`= 0.3 xx 330`
`= 99.0 m `
