Question

Velocity of sound I'm air is 360m/s and frequency of a tuning fork is 660 hz. What will be the distance covers by the a sound is 200 complete vibration of the fork? ​

Answer 1

Answer:

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(

256

350

)

$$= 21.875$$

d=21.875m

Answer 2

d=21.875m
