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

Answer

18 m

Explanation

Here, `v = 560 Hz, v = 336 m//s, lamda = (v)/(v) = (336 m//s)/(560 //s) = 0.60 m`
Distance covered by sound during 30 vibrations `= 30 lamda = 30 xx 0.6 = 18 m`.
