Question

Find wavelength of sound waves in air generated by tuning fork of 256Hz at 54degree celsius Assume velocity of sound at NTP as 330 m/s
​

Answer 1

Answer:

21.875 m

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
