Question

Calculate the wave length of a sound wave whose frequency is 220hz and speed is440ms-1

Answer 1

$\bold{Answer:}$

Question: Calculate the wavelength of a sound wave whose frequency is 220 Hz and speed is 440 m/s in a given medium.

Solution: Frequency of the sound wave, ν= 220 Hz ,

Speed of the sound wave, v = 440 m s-1 ,

For a sound wave,

Speed = Wavelength x Frequency v = λ x ν ,

ˆ´ λ= v / ν = 440 / 220 = 2m ,

Hence, the wavelength of the sound wave is 2 m.
