Question

The frequency engraved on a tuning fork is 256 Hz. What time does a prong of tuning folk take

to complete one vibration​

Answer 1

Answer:

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

n=256Hz,

v=350

s

m

no. of vibrations =16

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

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

λ= n/v

d=16λ

=16( 266/350)

$$= 21.875$$

d=21.875m
