Question

The frequency of a tuning fork is 256 Hz and velocity of sound in air is 350 m / s. Find the distance covered by the wave when the fork completes 16 vibrations

Answer 1

Given :

n = 256 Hz,

v = 350 m/s  

no. of vibrations = 16

Distance covered by wave in one vibration is its wavelength (λ)  

∴ Distance covered by wave in 16 Vibrations = d = 16 λ  

λ = v/ n  

∴ d = 16λ  

= 16 v/ n

= 16( 350/ 256)

= 21.875

∴ d = 21.875 m
