How far does sound travel in air when a tuning fork of frequency `560 Hz` makes `30` vibrations ? Velocity of sound is `336 m//s` ?

Explanation

Distance travelled by sound when tuning fioek makes one vibration, `lamda = (v)/(v) = (336 m//s)/(560 Hz) = 0.6 m`
Distance travelled by sound when tuning fork makes `30` vibrations `= 30 lamda = 30 (0.6 m) = 18 m`.
