Question

A tuning fork vibrates with a frequency of 256hz if the speed of sound is 345.6m/s find the wave length during the time the fork makes 60 vibrations

Answer 1

Given, Frequency, n = 256Hz
velocity of sound, v = 345.6 m/s
wavelength, λ = ?
No. of vibration made = 60
By using the relation , v = nλ
λ = v/n = 345.6/256 = 1.35 m
Distance travelled by sound = Wavelength X No. of Vibrations
= 1.35 X 60
= 81.0 m (Ans.)
