Question

velocity of sound in air in 330 m per second and frequency of a turning fork is 360 hz what will be the distance covered by the sound is 200 complete vibration in the fork? [ Ans : = 100 m ]​

Answer 1

Answer:

Explanation:

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
