see speed is 340 let's take it as its speed is equal to speed of sound

and velocity = wavelength*freqiency then find it

speed of sound = V
wavelength = λ
frequency = v
the time period of a wave is represented by = T = 1/v
In time T, a distance of wave length v is covered
so the speed of sound = V = λ/T
or V = λv
