The wavelength depends on the speed of sound and can be calculated as

λ = c / f           (2)

where 

λ =  wavelength (m)

cspeed of sound (m/s)

f = frequency (s-1, Hz)

 Sound velocity depends on the density of the air and the air temperature. Typical value for speed of sound is 343 m/s for temperature 20oC.
