Sound&#039;s frequency stays the same across mediums. To find it&#039;s frequency, we can use   v  =  λ  f inputting knowns:  330      m    s    =  5.5  m  ∗  f Solve for f:f=60HzKnowing this, we can find the wavelength   λ in the other medium:  v  =  λ  f Inputting knowns:  1324      m    s    =  λ  ∗  60  H  z Solve for   λ  :  λ  =  22         2    3    m or   λ  =  22.67  m in decimal form.
